function rowNum=findrow(str,strMat)
%FINDROW Find the rows of a matrix that match the input string.
%   ROWNUM = FINDROW(STR,STRMAT) returns the index to the row or rows
%   in the matrix STRMAT that are identical to the vector STR.
%   Blanks (ASCII 32) and zeros are not considered. An empty matrix 
%   is returned if there is no match.
%
%   For example:
%
%   strMat = fstrvcat('one','fish','two','fish',[1 2 3 4 5 6]);
%   rowNum = findrow('fish',strMat)
