Comparing strings:

There are few functions which compare strings and return logical true when they are equivalent or logical false when not. The function strcmp compares the strings, character by character. It returns the logical true if strings are completely similar (it also infers that they should be of similar length) or logical false if the strings are not of similar length or any equivalent characters are not identical. Here are some illustrations of such comparisons:

>> word1 = 'cat';

>> word2 = 'car';

>> word3 = 'cathedral';

>> word4 = 'CAR';

>> strcmp(word1,word2)

ans =

0

>> strcmp(word1,word3)

ans =

0

>> strcmp(word1,word1)

ans =

1

>> strcmp(word2,word4)

ans =

0
