Cell array to matix

i have cell array of 1x112 cell

each cell consists of mx3 matix

i want to get all matix in the cell array as seprate martrix in workspace

[madhan ravi]

So you want to convert cell array as one matrix or separate matrices?

i have cell array of 1x112 cell

each cell consists of matix of variable sizes

i want to get all matix in the cell array as seprate martrix or array in matlab workspace

I guess you want to load the file so that the data appear in workspace if so then

load microtip % where microtip is the name of .mat file

[Praveen Kumar Ramani]

Sir i have loaded in workspace,

i want each matix from a cell array to be separated as a single single matix which should be appear in my workspace

[madhan ravi]

OK , upload your data file,

Remark: As seen from the picture each cell has different matrix sizes.

Target: When you say separate matrix what do you want the size of each matrix to be , remember each should have the same size when concatenated along the third dimension. If you say it should have the same size as the original form then keeping it as cell is the only way. So your call..

You could try using:

M = {}; % Your cell
N = cat(3,M{:}); % Concatenate matrices along 3rd dimension

This will give you a single matrix rather than 112 separate matrices.

"i want to get all matix in the cell array as seprate martrix in workspace"

The follow-ups to that question will be how do I create the variable names dynamically, how do I loop over all these variables or something similar.

The answer: Don't do that. Your matrices are perfectly usable as they are. You don't need them as separate variables, it is much easier to keep them as a cell array. Dynamically creating 112 different variables would be madness. It would be slow, hard to debug and you wouldn't be able to use them efficiently.

If you explain what you want to do with these 112 matrices, we can show you how to use that cell array properly.

I want all the matrix one by one to be an input for matlab function

Trivially done with a cell array:

for i = 1:numel(Microtrips)
    result = somefunction(Microtrips{i})  %call function with each matrix in turn. 
    %... some more code
end
