Seems you want to have powers from 1 to 4
v = 1:4;
bsxfun(@power,v(:),[1:4]) % poers ranging from 1 to 4
ans = 4×4
1 1 1 1 2 4 8 16 3 9 27 81 4 16 64 256

  • Take transpose of vector a to make it a row vector.
  • Take square of a and put the result in second column
  • Take cube of a and put the result in third column.
  • Use index of for loop with .^ to take square, cube, etc
