I have 5 vectors y1, y2, y3, y4, y5 of variable number of samples or values. I have created a cell array as:

vectorarray = {y1, y2, y3, y4, y5}

I know the classic way of finding the largest number of samples in the elements of the cell array can be done as follows:

maxsamples = 0
for k = 1:numel(vectorarray)
    currveclength = length(vectorarray{k})
    if currveclength > maxsamples
        maxsamples = currveclength
    end
end

Is there a simpler way to do it in a single line in Matlab?
