Replacing values in cell array in for loop

I have cell array {1x5} and each cell contains 1000x1000 matrix. I need to find values which are less than 100 and replace it with 100. I tried with cellfun but i couldn't get the right solution.

Can anyone help me with that?

Y(cellfun(@(Y) Y < spect_threshold, spect_threshold, 'UniformOutput', false));

It is simpler and more efficient to use max:

F = @(m) max(m,spect_threshold);
Y = cellfun(F, Y, 'UniformOutput', false);

What does the first line mean? can you please eleborate.

Thanks

The first line defines an anonymous function (called "lambda function" in some other languages):

The function has one input m and for each element in m returns either its value or spect_threshold, whichever may be greater. cellfun applies that function to each matrix in the cell array.
