Dear all

i got this error

Error using horzcat

Dimensions of arrays being concatenated are not consistent.

Error in dmatrix (line 9)

sp3=reshape([se./sd 0],181,251,391);

the code is

clear
load sr1695.asc
load sr1698.asc
sd = sr1695;
se = sr1695;
%The following forms 3D matrices, then a 2D projection along Z which eliminates the Z dependence.
sd3=reshape([sd(1:17763520) 0],181,251,391);
sp3=reshape([se./sd 0],181,251,391);
sd2=squeeze(mean(sd3,3));
sp2=squeeze(mean(sp3,3));
p2=hist3([reshape(sd2,1,[])', reshape(sp2,1,[])'],'Nbins',[100,100]);

thank you

se and sd are presumably arrays with exactly 181 * 251 * 391 elements. However 0 is not. You're going to have to make 0 an array with the same number of rows and columns if you're going to stitch it next to the ratio array.

[rows, columns,slices] = size(se)
if rows*columns*slices == (181 * 251 * 391)
    z = zeros(size(se));
    stitchedArray = [se./sd, z];
    sp3=reshape(stitchedArray, 181, 251, 391);
else
    message = sprintf('Wrong number of elements to reshape.\nRows = %d, columns = %d, slices = %d, and product = %d\nbut (181 * 251 * 391) = %.1f', ...
        rows, columns, slices, rows*columns*slices, (181 * 251 * 391));
    uiwait(errorsld(message));
    return;
end
