Convert cell to array
显示 更早的评论
Hi everyone,
I have a cell array 64x1 and I would like to convert in array 64x1, but when I use cell2mat I obatin this result:
180672064x1
Why? How can I resolve this problem?

Please post you cell array and code.

It looks like your cell array of size 64x1, in there each cell has a array of size 2823001x1. If not you need to provide what is the data and class present in each cell array.

...or perhaps transpose the cell-array and convert that into what should become a 2-D array:
m2D = cell2mat(c_arra');
The size of m2D should now be something like 2823001 x 64. Perhaps that is what you're after.

64 means sixtyfour. My suggestion would give you one two-million-eighthundred-twentythree-thousand and one by sixtyfour array, that is an array with sixtyfour columns and 2823001 rows.
The reason you get sub-quality answers is that it is not clear what you want to achieve from your question.

Felicia, the elements in your cell-array are themselves arrays, as @KSSV pointed out. When you call cell2mat the contents of the cells are merged, if that is possible, into one array. For this to work the sizes of the elements have to match the right way. For your case, you can check what sizes the cells-contents are by simply typing the name of the cell-array variable at the command-line prompt.
For your expressed objective to make sense you will need to decide which element of each cell you want to extract into your ordinary array. If it for example is the second component in each element you can do something like this:
for i1 = 64:-1:1
a_regular(i1) = cell_variable{i1}(1);
end
