To create:

A $3\times 6$ matrix of random integers, each in the range from 50 to 100. Write this to a file called randfile.dat. Then, create a new matrix of random integers, but this time make it a $2\times 6$ matrix of random integers, each in the range from 50 to 100 and append this matrix to the original file.
