CELL2MAT Convert the contents of a cell array into a single matrix. & g# k9 z- v# ^ M = CELL2MAT(C) converts a multidimensional cell array with contents of; _$ w3 _ M" Y
the same data type into a single matrix. The contents of C must be able ; d1 [0 W; m% i+ q j, `8 \ to concatenate into a hyperrectangle. Moreover, for each pair of / f9 Q2 a8 \, j, e# t+ a9 r neighboring cells, the dimensions of the cell's contents must match, 7 C( S' q/ J0 P# ? excluding the dimension in which the cells are neighbors.

仔细看下mat2cell命令，不只能转化成1*1的cell。 . u8 e/ ?% F" t ) v& N& A; G# i# J( Mn = 10;6 @+ ?( l6 Z/ E
