From a cell to an array (besides cell2mat)

Let's say I have a cell called path, which consists of the following, for illustration purposes, [0] [1x2] [1x3].

Is there any way to transform it into a normal array, such that if I wanted to access, for example, path(1) = 0, path(2) = 1 2 and path(3) = 4 5 6 ( the values are just for illustration purposes).

Thanks for the help in advance.

Why not cell2mat? What problem you have with it?

@Nuno Palma: do not call your variable path, because path is a very important function that will not work when you redefine its name. For the same reason never use the variable names size, length, cell, i, j, struct, etc.

"transform it into a normal array" What is a normal array? MATLAB does not have any data type named "normal". Do you mean a numeric array?

If you mean a numeric array then your examples

 path(1) = 0, path(2) = 1 2 and path(3) = 4 5 6

make no sense because one element of a numeric array contains exactly one value, so it cannot have two, three, or more values. If you want one element to have multiple value then use a cell array.

If all cells have a 1xN dimension, concatenation into a single row using comma-separate list expansion should work:

C = {[1] [2 3] [4 5 6]}
M = cat(2, C{:})

[Stephen23]

Actually this works for any MxX dimensioned arrays, where each array can have different X.

Sure.

C = {[1] [2 3] [4 5 6]}
result = [C{:}]
