Error_Unable to perform assignment because brace indexing is not supported for variables of this type

1 view (last 30 days)
I am keep getting an error: Unable to perform assignment because brace indexing is not supported for variables of this type.
Can someone please help me out to resolve the error?
for i = 1:size(platemap,1)
S = zeros(size(platemap,1));
G = zeros(size(platemap,1));
[S{i,1},G{i,1}] = cellcyclestages('f',Data{i,1},params,opts);
end
Thank You

What is Data? Hopefully it's a 2-D cell array. Or at least a 1-D cell array.
What does the cellcyclestages() function return? Two scalars? If so you don't need cell arrays. Vectors whose length may change from one iteration to the next? If so, then you need cell arrays.
See the FAQ for a nice discussion of cell arrays:
Try
numValues = size(platemap,1);
S = cell(1, numValues);
G = cell(1, numValues);
for k = 1 : numValues
[S{k}, G{k}] = cellcyclestages('f', Data{k,1}, params, opts);
end

Repaired code, no loop.
i = size(platemap,1);
[S{i,1}, G{i,1}] = cellcyclestages('f',Data{i,1},params,opts);
You do not need a loop because your existing code overwrites all of S and G every iteration of the loop, so your code only remembers what was done on the last iteration; so you might as well not any other iterations.
The recommended code would have been different if you were not overwriting all of S and G every iteration.
