MATLAB: Optimise for loop in using cell array

cell arrayfor loopoptimization code

Is it possible to do same without for loop?

    lengthboundaries=zeros(length(boundaries),1);
    for i=1:length(boundaries)
        lengthboundaries(i)=length(boundaries{i});
    end

Best Answer

lengthboundaries  = cellfun(@length,boundaries);

for i=1:100
   a{i} = zeros(366,28);
end

Loop through each cell array block and insert a zeros matrix inside.

MATLAB: How to optimise the code with cell

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});
