If constname is 146x4 char array (column vector of 146 4-character strings, I need the following command to return the index number of the string 'M12 '. But it doesn't. strfind doesn't work with arrays of strings. Which command does? My only option right now is a for loop and the strcmp command, which works, but, hey, this is Matlab!
index = strfind(constname,'M12 ')

Convert your 146x4 char array to a 146x1 cell array and then use strfind:
A = repmat('friday',146,1);
B = num2cell(A,2);
strfind(B,'fri')

Thanks, Sean. Fantastic resource. First time i used it!
The following works for me:
B = num2cell(constname,2)
[dex, bol] = find(strcmp(B,'M12 '))
Now my quibble. The docs say nothing about num2cell converting character strings to cells ala str2cell.
But thanks. It's done!

Great!
Please accept this answer, to mark the question closed.
It does say num2cell takes any type of array.
