Find a word in structure

Ik like to find a word (example:cat)in a structure field (by example: structureA.field1). How can you do that?

One approach:

structureA=struct;
structureA.field1="cat";
strfind(structureA.field1,"cat")

It will return 1 since the number of cat word in second argument of strfind function is 1.

"It will return 1 since cat word occurs one time in your field."

Actually it will return 1 because that is the index position of where the string "cat" was found. strfind's output is not a count of how many times the string was found: the number of elements in the output corresponds to how many times the string was found.

Ups yes, I read the documentation incorrectly. Let me edit it.

Erik Verdijk's "Answer" moved here:

structureA=struct;
structureA.field1="cat";
strfind(structureA.field1,"cat")

I get the message:

Error: File: negenentwintigmaart.m Line: 8 Column: 12
The input character is not valid in MATLAB statements or expressions.

What Did I wrong?

@Erik Verdijk: What version of MATLAB are you using?
