eytract the smalles value out of a cell array in matlab

You can use the cellfun function in MATLAB to extract the smallest value out of a cell array. Here is an example code snippet:

main.m
% create a test cell array
C = {[1 2 3], [4 5], [0 -1 2 7]};
% get minimum value across all cell array elements
min_val = min(cellfun(@min, C));
disp(min_val);
160 chars
6 lines

This code snippet will output -1 as the result, which is the smallest value across all the cell array elements.

The cellfun function applies the min function to each cell array element using the @ operator. The min function then returns the smallest value for each cell array element. Finally, the min function is called again to find the minimum value across all the elements.
