I really need help with MATLAB! I was given a 3d matrix. I'm supposed to write a matrix indexing code containing a variable that will contain ONLY every other row from the first matrix. The 1st, 2nd, and 3rd columns of the new matrix should be the 1st, 3rd, and 5th columns of the original and so on. The original matrix is really big, like 108x103, so it's very hard to figure out! Please help!
