I have two cell arrays. In one cell, there is a value of the matrices with dimension 100 by 10 and other cell there is row and column number of the matrices100 by 2. the array length is same i.e. 10 for both. Now, I want to find out the the cell array with having the values from matrix (100 by 10), whose index is matched with other matrix (100 by 2).
But this error is coming 'Unable to use a value of type 'cell' as an index'. Please help me solve it.
T3=num2cell(tr1,1); % having values
V1=num2cell(v,1) % having rows and columns for 10 arrays
T3=T3';
for k1=1:10;
sigval{k1}=T3(V1(k1,1),:);
end

Error is coming in your command "Unable to use a value of type 'cell' as an index"
If I write it for every column for matrix A it matrix but when I write it for all column it is not working
for k1=1:10;
sigval1=tr1(V1{1,1}(1:1801,1),1); % for 1st column, it working
%sigval1(:,k1)=tr1(V1{k1,1}(1:1801,1),k1); % for all columns but this command is not working
end
