how to optimise the code with cell?
显示 更早的评论
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)

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});
