So I am looking to create an array that is 2 dimensional for all columns except for one.

So for example,

Column A B C D E are 2D
F is 3D with every element itself being an array

So I want to create a matrix that looks like this

A B C D E F*

..
..
..
..

I cannot figure out how to do this without getting dimensionality issues.

Though I am not an expert in MATLAB code, I would like to suggest you that you should use cell arrays to contain matrices with unequal dimensions. I will try to explain it by following example:

Let us say:

A = [1 2 3 4];
B = [5 6 7 8];
C = [9 10 11 12];
D = [13 14 15 16];
E = [17 18 19 20];
F = magic(3);
combined_array = {A B C D E F};

In this case combined_array{1} will give matrix A, combined_array{2} will give matrix B and so on..

It means that combined_array{6} will give matrix F.

I guess this would help you.

An array in MATLAB MUST be rectangular (all the rows have the same number of
columns, all the columns have the same number of rows, all the pages have
the same number of rows and columns, etc.) Therefore there is no way to do
what you want, unless you store each of your arrays inside a cell in a cell
array. In that case, while the contents of the cells may be different sizes
or may have different numbers of dimensions, the cell array as a whole is
rectangular.
