Matlab里怎么把元胞数组的内容转化为矩阵？（元胞数组的每个元胞都是double型的数）。

CELL2MAT Convert the contents of a cell array into a single matrix.
M = CELL2MAT(C) converts a multidimensional cell array with contents of
the same data type into a single matrix. The contents of C must be able
to concatenate into a hyperrectangle. Moreover, for each pair of
neighboring cells, the dimensions of the cell's contents must match,
excluding the dimension in which the cells are neighbors. This constraint
must hold true for neighboring cells along all of the cell array's
dimensions.

The dimensionality of M, i.e. the 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.

      Example:
         C = {[1] [2 3 4]; [5; 9] [6 7 8; 10 11 12]};
         M = cell2mat(C)

      See also mat2cell, num2cell

help cell2mat

仔细看下mat2cell命令，不只能转化成1*1的cell。

n = 10;
a = rand(n);
acell = mat2cell(a,ones(n,1),ones(n,1));
