Suppose B = [1, 2 3; 4, 5,6; 7,8,9], write a program with “for” loops that calculate the square of B.

in MATLAB

You don't really need the for loop to calculate B square.

The element-wise multiplication operator can help you get the square of each element of B.

B = [1, 2 3; 4, 5,6; 7,8,9];

B = B.^2;

Hope this helps!

look at the engine block shown in the figure. the engine shown in this figure is a/an  

  a. four-cylinder, horizontally opposed engine.

  b. eight-cylinder, v-type engine.

  c. six-cylinder, v-type engine.

  d. four-cylinder, in-line engine
