k = isstr(t)
t = 'Hello, World.' creates a vector whose components are the ASCII codes for the characters. The column dimension of t is the number of characters. It is no different than other MATLAB vectors, except that when displayed, text is shown instead of the decimal ASCII codes.
Associated with each MATLAB variable is a flag that, if set, tells the MATLAB output routines to display the variable as text.t =Hello, World.
isstr(t) returns 1 if the text display flag for t is set, and 0 otherwise.
isstr also works on matrices.
isstr('Hello') is 1.
isstr(abs('Hello')) is 0.
