how to optimise the code with cell?

for this program i am calculating A by using for

A = cell(1,3);
for k = 1:3
    A{k} =  B*k + C*k;
end

And then every matrix is to be compared to get a Optimal matrix containg minimum of every every A matrix

Comparison = cat(3,A{1},A{2},A{3});
MinimumMatrix = min(Comparison./(Comparison~=0),[],3);

This is a example code

Nut in actual program i have to calculate

k=1000:10:5500

What function should be used in

Comparison = cat(3,A{1000},A{1010},..  A{5500});

to avoid writing the name of each variable for comparison matrix

cellfun(@(x)min(x),A,'un',0)

oops I misinterpreted please upload cell A as .mat file

Why are you using cell arrays in the first place? It's just slower and has more overhead than matrices. You can just create your final matrix directly

stepcount = 3
A = zeros([size(B), stepcount]);
for k = 1:stepcount
    A(:, :, k) = B*k + C*k;
end

If you really want to use an intermediate cell array, then you can use the expansion of cell arrays into comma-separated lists:

Comparison = cat(3,A{1},A{2},A{3});
%is equivalent to
Comparison = cat(3,A{:});

Comparison = cat(3,A{1000},A{1010},..  A{5500});
%is equivalent to
Comparison = cat(3,A{1000:5500});

Actually i was using eval

but after getting some error i switched to cell....

will try stepcount now

It was really helpful

thank you
