MATLAB loop structure: While statement p69 norm to be compiled

1. The general format of the while statement is:

While condition loop body statement end

1. Enter several numbers from the keyboard. When the input is 0, end the input and calculate the average value of these numbers and their sum.

The procedure is as follows:

Sum = 0; n = 0; X = input ('enter a number (end in 0): '); While X ~ = 0 sum = sum + X; n = n + 1; X = input ('enter a number (end in 0): '); endif (n> 0) summean = sum/nend

Output:

Enter a number (end in 0): 555656
Input a number (end in 0): 2
Input a number (end in 0): 2
Input a number (end in 0): 2
Enter a number (end in 0): 20
Input a number (end in 0): 0

Sum =

555682

Mean =

1.1114e + 005

1. Calculate the matrix index based on the idempotence expansion of the matrix Index
