Speed comparison. Using the command "tic, toc" to measure the elapsed time of the computation. Compare NGE or GE P.P and LU.in terms of their speed. In order to view their difference, please write a for loop to repeat the same process for 10,000 times (to magnify the time differences of computing.). 21000000121000000121000000121000000121000000121000000121000000122=344444431 2100000012100000012100000012100000012100000012100000012100000012=75555555 2100000012100000012100000012100000012100000012100000012100000012=12132233
