How make the number of columns of two matrices equal?

There are a number of possibilities. Off the top of my head:

• You could discard 1100 columns of the second matrix (the first 1100, the last 1100, half from the left and half from the right, etc.)
• You could pad the first matrix with 1100 more columns (full of all 0 values, full of NaN values, duplicates of 1100 columns from that matrix, etc.)
• You could interpolate one of the matrices so that they span the same "range" as the original but the spaces between columns is different (take hourly data and interpolate it to data with spacing of a minute, for example.)

What is the (or a) correct solution for your data depends on what it represents and how the two matrices relate to one another.
