I have a matrix A= [ 2 3 2.1 ; 8.1 3.3 2.05 ; 3.01 4.9 2.09] and I want to get the mode with a tolerance of 0.1 there is any way to get this??? to work in matlab with mode (the value most repeated) and tolerance thanks

The question is not trivial. What do you expect as result for:
x = [0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6]
?
You can round the values:
AA = round(A, 1)
and apply mode() afterwards, but this must not be necessarily, what you want.

One can bin the data with the required tolerance and return the center of the bin with the highest frequency. I'm not particular about the tolerance, so I'm doing it as follows:
[N, edges] = histcounts(data);
[~, idx] = max(N); mode = (edges(idx) + edges(idx + 1))/2;
It would be nice if there was a built-in function for this.
