Error Using Accumarray "Requested array exceeds the maximum possible variable size"
显示 更早的评论
I am trying to generate a histogram but I keep on getting this error
Error using accumarray
Requested array exceeds the maximum possible variable size.
Error in Analyze (line 170)
zm=accumarray([Dfr' Zfr'],1,[nn nn]);
My code is here
n=100;
for i=1:1
ZZ=Zf{i};
DD=Df{i};
nn=repelem(n,144);
Zf2=linspace(min(ZZ(:)),max(ZZ(:)),n);
Df2=linspace(min(DD(:)),max(DD(:)),n);
Zfr=interp1(Zf2,1:numel(Zf2),ZZ,'nearest');
Dfr=interp1(Df2,1:numel(Df2),DD,'nearest');
zm=accumarray([Dfr' Zfr'],1,[nn nn]);
figure, surf(zm);
hold on
end
A segment of Df and Zf are pictured above

nn=repelem(n,144);
That is a vector of 144 copies of 100
[nn nn]
that puts two of those together, getting a 1 x 288 vector of 100's.
You are requesting that accumarray create an output that is 100^288 elements.
There are only roughly 3*10^80 particles in the observable universe.
