If your data looks like

a={{1:2 3:4 5:6};{7:8 9:10 11:12}}

Use

out=cell2mat([a{:}]')

If the vector sizes allow it, you could save your three numeric vectors together as one matrix, then this also removes the need to have one more level of nested cell arrays.

This means instead of

data_matrix = {{num_1x21,num_1x21,num_1x21};{num_1x21,...};...}

you can store it as

data_matrix = {num_3x21;num_3x21;...}

Even better would be to remove the cell array entirely:

data_matrix = num_Nx21

Keeping all the data in a numeric array has multiple advantages:
