MATLAB: Help with plotting needed!

Question

Hello all.

I have 100 element cell array, and each element represent a lund cell. Each element in cell array is av matrix of 1X1000 of intensities (each element in this matrix is the data recording per hour). I want to plot each lund cell (100 of them) on a raster plot with x as the time axis and the lund cell # on the y-axis.

I am not sure how to plot all the matrices of all 100 cells using imagesc and was wondering if I could please have some urgent help. Thank you in advance.

Answer 1

Assuming that the intensities are numeric and that each element in the cell array is a matrix of 1x1000 dimension, then why not just concatenate all of the data together into a 100x1000 matrix, where each row in the matrix is the 1000 intensities for a single lund cell?

 lundCellData = zeros(100,1000);
 for k=1:100
    lundCellData(k,:) = cellArray{k}; % cellArray is the 1x100 element cell array
 end

And then just use imagesc to plot the data

 imagesc(lundCellData);

This will plot the time data along the x-axis, and the lund cell numbers along the y-axis.

Try the above and see what happens!
