STRCMP String Compare Function

Section: String Functions

# USAGE

Compares two strings for equality. The general syntax for its use is

      p = strcmp(x,y)

where `x` and `y` are two strings. Returns `true` if `x` and `y` are the same size, and are equal (as strings). Otherwise, it returns `false`. In the second form, `strcmp` can be applied to a cell array of strings. The syntax for this form is

      p = strcmp(cellstra,cellstrb)

where `cellstra` and `cellstrb` are cell arrays of a strings to compare. Also, you can also supply a character matrix as an argument to `strcmp`, in which case it will be converted via `cellstr` (so that trailing spaces are removed), before being compared.

# Example

The following piece of code compares two strings:

    --> x1 = 'astring';
    --> x2 = 'bstring';
    --> x3 = 'astring';
    --> strcmp(x1,x2)

    ans =
     0

    --> strcmp(x1,x3)

    ans =
     1

Here we use a cell array strings

    --> x = {'astring','bstring',43,'astring'}

    x =
     [astring] [bstring] [43] [astring]

    --> p = strcmp(x,'astring')

    p =
     1 0 0 1

Here we compare two cell arrays of strings

    --> strcmp({'this','is','a','pickle'},{'what','is','to','pickle'})

    ans =
     0 1 0 1

Finally, the case where one of the arguments is a matrix string

    --> strcmp({'this','is','a','pickle'},['peter ';'piper ';'hated ';'pickle'])

    ans =
     0 0 0 0
