I had a previous problem where I wanted to replace any string 'Bad' with NaN.
A forum member suggested the following code which works a treat;
buffer = strrep(buffer, 'Bad', 'NaN') ;
Is there anyway I can modify this so that any string which appears in the matrix is replaced by NaN rather than just the 'Bad'?
Many thanks in advance

can you give an example of your matrix?

My measurement file usually inserts bad when a measurement couldn't be made however some floating point have been corrupted and Want to replace these (as well as the 'Bad's with NaN.
For example
Bad Bad Bad -6.54
-6.41 -6.32 -6.01
-6.14 -6.t4 Bad
In this case I want the -6.t4 to be replaced with NaN as well as the Bads

a={'Bad' 'Bad' 'Bad' -6.54; -6.41 -6.32 -6.01 -6.14 ;-6.4 'Bad' 1 2}
b=cellfun(@num2str,a,'un',0);
a(ismember(b,'Bad'))={nan}
