Matlab table to matrix.

t = table (year,month,day,pr) which creates a table with four variables, one of which itself has 30888 columns. And as Andrei said, a timetable might be the way to go if you have R2016b or later. Of course, if you are just using the table to write to a file via writetable, then you don't need a timetable. You could still convert day,month,year ...1. B=A'; B (:)'. Walter Roberson on 16 Aug 2015. Using ' instead of .' makes extra work because ' is conjugate transpose. Your code does the conjugate transpose twice so you do end up with the original values, but it is work that doesn't have to be done. Sign in to comment.

See the error message and the solution …Description. B = rowfun (func,A) applies the function func to each row of the table or timetable A and returns the results in the table or timetable B. The number of inputs that the function func accepts must equal the number of variables in A. For example, if func must be called with two input arguments, then A must have two variables.

Easy to use and very flexible: - takes MATLAB matrices, cells or tables as input. - gives code for a LaTeX table containing your data as output. - handles numeric and text/string data. - easy including in your code for automation. - easy direct saving as a LaTex document (see example 2 in runExamples.m) Optional features are: - table positioning.Categorical Arrays. Arrays of qualitative data with values from a finite set of discrete, nonnumeric data. categorical is a data type to store data with values from a finite set of discrete categories. For example, the syntax C = categorical ( {'R','G','B','B','G','B'}) creates a categorical array with six elements that belong to the categories ...

C = union(A,B, ___,'rows') and C = union(A,B,'rows', ___) treat each row of A and each row of B as single entities and return the combined rows from A and B, with no repetitions.You must specify A and B and optionally can specify setOrder. The 'rows' option does not support cell arrays, unless one of the inputs is either a categorical array or a datetime array.T = table (T1,T2,T3) only works if all three tables have exactly the same number of columns AND exactly the same number of rows, and all columns are the same data type. If I had a 1000 tables, it would be nice if Matlab could index them: T (1) = …

I have a MxN matrix made of strings and I would like to convert it into a table because I need to have a timetable object in the end. My variable is a 720x2 strings, the first column contains the timestamp and the second contains a integer value.Description. m = missing returns a missing value displayed as <missing>. You can set an element of an array or table to missing to represent missing data. The value of missing is then automatically converted to the standard missing value native to the data type of the array or table variable. For example, core data types that support missing ...example. stats = grpstats (X,group) returns an array with group summary statistics for the columns of the matrix X, where the function determines the groups by the grouping variables in group. If X is a numeric or logical matrix, then the summary statistic is the mean of each group for each column of X . Otherwise, the summary statistic is the ...

It is my understanding that you want to create a table which consists of string and double in columns. You can use table function which can accept array with named variables that can contain different data types. The example code is given below:

The panel looks like this and the code for the push button is To create a multiline title, specify a cell array of character vectors or a string array. Each element in the array corresponds to a line of text. Example: h.Title = {'My','Title'}; If you specify the title as a categorical array, MATLAB ® uses the values in the array, not the categories.

"The VariableNames property must be a cell array, with each element containing one nonempty character vector." found in the table VariableNames documentation. So the problem is solved by being able to convert the string array, Header, to a cell array of character vectors. This is achieved using the cellstr function.No, *100. You have 01:13:00 and you want to see 113 from that. hour () of this is 1, and minute () of this is 13. If you multiplied the 1 by 60 and added 13 you would get 73, number of minutes into the day, which is potentially a valid thing to want to see, but your example output requested 113 which is 1*100+13.clear all. clear. filename=uigetfile ('*.dat'); A=readtable (filename,'Delimiter','\t'); I know get a table with the format 370x1, which is useless to me, because I am trying to do a surf plot with all the numeric data on the right. The Table I get looks like this:Array Comparison with Relational Operators. Relational operators compare operands quantitatively, using operators like “less than”, “greater than”, and “not equal to.”. The result of a relational comparison is a logical array indicating the locations where the relation is true. These are the relational operators in MATLAB ®.Description. C = table2cell (T) converts the table or timetable, T, to a cell array, C. Each variable in T becomes a column of cells in C. The output C does not include the table properties in T.Properties. If T is a table with row names, then C does not include the row names.For array input data, groupvars can be either a column vector with the same number of rows as A or a group of column vectors arranged in a matrix or a cell array. For table or timetable input data, groupvars indicates which variables to use to compute groups in the data. You can specify the grouping variables with any of the options in this table.
