How do I concatenate multiple arrays?

Hi, I am trying to concatenate multiple arrays with different numbers of rows but the same number of columns. I would like to create a new array by joining together other arrays, such that the rows are essentially added onto the other array and the columns align with the those of the other array. Say if I have an array 'A' which is a 76 x 900 double and array 'B' which is a 50x900 double, I would like it so the new array is a 126x900 double.

At the moment, the code I am using is adding on additional columns instead of new rows:

new_array = [A, B];

Any suggestions would be greatly appreciated, thanks in advance
