Question

[Sorry for the dumb question. I’m completely new to MATLAB (and completely bewildered by it).]

I want to write a function to2d, taking as its only argument an m x 1 cellarray of 1 x n cellarrays, and returning the corresponding m x n cellarray.

For example, we would get stuff like:

>> A = {{1, 2}; {3, 4}; {5, 6}}

A = 

    {1x2 cell}
    {1x2 cell}
    {1x2 cell}

>> B = to2d(A)

B = 

    [1]    [2]
    [3]    [4]
    [5]    [6]

This question may be thought as a special case of the more general problem of programmatically passing arguments to a variable-arguments function when all one knows about these arguments is that they are stored in some cellarray. In Python, one does this by using the *-syntax. E.g.

func_with_indeterminate_args(*a_runtime_list_of_args)

Thanks!

Just what the function cat doing:

>> cat(1,A{:})
ans = 
    [1]    [2]
    [3]    [4]
    [5]    [6]
