How to reference values in cell array containing matrices
Mostrar comentarios más antiguos
I have a cell in which each element is a matrix. I would like to extract a vector containing all the matrices' entries for row 5, column 4. Is this possible, without having to loop through the matrices and extract the value? Here's an example,
% Create the cell array
for iMatrix = 1:10
a{iMatrix} = rand(12, 13); % Each element of this cell array is a matrix
end
iRow = 5; iCol = 4; % Indices to the value to extract from each matrix
% Unsuccessful attempts
a{:}(iRow,iCol)
Expected one output from a curly brace or dot indexing expression, but there were 10 results.
a(:)(iRow,iCol)
Error: ()-indexing must appear last in an index expression.
a(iRow,iCol)
Index exceeds matrix dimensions.
