How to select and plot the maximum point in several pixels

Hello,
I have a data set ( called TVL.Volume) from a spectrometer reading. The data is in the form of a matrix.There are 4096 pixels in the data set, while the rows and column are 104 and 60 respectively. Each pixel is a representation of a waveform. I want to select the maximum amplitude of the waveform of each pixel in all the rows and column, then plot the points as an image. Please find below my attempted code; the code does not work as expected. thank you for your anticipated response
%TVL.Volume is a matrix whose size is 4096 X 104 X 60
s= size(TVL.Volume);
for i = 1:s(2);
for j = 1:s(3);
a(i,j)=max(TVL.Volume(:,i,j));
end
end

A = rand(4096,104,60) ;
B = permute(A,[2 1 3]) ;
B_max = max(B,[],3) ;
imshow(B_max)
