What does . do in matlab.

Description. while expression, statements, end evaluates an expression , and repeats the execution of a group of statements in a loop while the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false.Description. xticks (ticks) sets the x -axis tick values, which are the locations along the x -axis where the tick marks appear. Specify ticks as a vector of increasing values; for example, [0 2 4 6] . This command affects the current axes. xt = xticks returns the current x -axis tick values as a vector.Jan 12, 2017 · A function handle is a MATLAB® data type that stores an association to a function.

In MATLAB ® , the filter function filters a vector of data x according to the following difference equation, which describes a tapped delay-line filter. a ( 1) y ( n) = b ( 1) x ( n) + b ...

Count the number of occurrences of the string, red, in string arrays. You can create a string using double quotes. str = "paired with red shoes". str = "paired with red shoes". To count the occurrences of red, use the count function. In this example, the result is 2 because red is also part of the word paired.

Like @Praetorian said it to ignore value instead of creating a junk variable. But you can just try : [junk, idx] = min (cf (:)); to obtain the index of the minimum value in your matrix. astro replacement cable For example, MATLAB uses 3 digits to display int8 data types (for instance, -128:127). Setting the output format to short or long does not affect the display of integer-type variables. Integer-valued, floating-point numbers with a maximum of 9 digits do not display in scientific notation.Sep 26, 2013 · In other contexts, ~ is the logical not operator and ~= is a logical comparison operator for testing inequality.
