Have you ever run into a problem where you would want to merge 2 blocks/variables that are inequal in size? I have encountered this many times. For example: one variable has only one row containing patient details but other variable has 2 rows containing parameters for 2 eyes or 2 knees. How do you read this as a single patient? Well, this function will help you!

input ->
1. variable/block 1
2. variable/block 2
output ->
single block with rows equal to block which has greater length in 1st dimension. Cols will be equal to addition of the two blocks' columns
