new to Matlab -excluding data in plots?
(OP)
Hey,
I do have a data file 49 coloumns, 9 rows with data flagged as 99.99. Now I would like to plot these data using pcolor excluding the 99.99-data. (Saying, leaving this space white on the plot)
How can I do this?

RE: new to Matlab -excluding data in plots?
% 'A' is the matrix containing the data
% find the matrix indeces of the 99.99 data
idx = find(A==99.99);
% replace the 99.99 vales with the value 'NaN'
A(idx) = NaN;
% plot the data
pcolor(A);
Matlab interprets 'NaN' as 'Not a Number' and leaves that bit blank.
