MATLAB Function Reference |
Convert cell array of matrices to single matrix
Syntax
Description
m = cell2mat(c)
converts a multidimensional cell array c
with contents of the same data type into a single matrix, m
. The contents of c
must be able to concatenate into a hyperrectangle. Moreover, for each pair of neighboring cells, the dimensions of the cells' contents must match, excluding the dimension in which the cells are neighbors.
The example shown below combines matrices in a 3-by-2 cell array into a single 60-by-50 matrix:
Remarks
The dimensionality (or number of dimensions) of m
will match the highest dimensionality contained in the cell array.
cell2mat
is not supported for cell arrays containing cell arrays or objects.
Examples
Combine the matrices in four cells of cell array C
into the single matrix, M
:
C = {[1] [2 3 4]; [5; 9] [6 7 8; 10 11 12]} C = [ 1] [1x3 double] [2x1 double] [2x3 double] C{1,1} C{1,2} ans = ans = 1 2 3 4 C{2,1} C{2,2} ans = ans = 5 6 7 8 9 10 11 12 M = cell2mat(C) M = 1 2 3 4 5 6 7 8 9 10 11 12
