new to matlab simple question

when you do a computation ie c=(b+a)/2 will this automatically display in matlab? i'm new to MATLAB but not programming at all and was just wondering if there is a display command or if all calculations are displayed which would make most sense to me since MATLAB is just math calculations...

Yes it will, assuming that you have previously defined the values for a,b,c obviously.

If you write semicolon at the end of your c=(b+a)/2; then it won't display.

okay wait, so to display the command you just leave out the semi-colon am I understanding that right? Also one more thing..

Sorry more beginner stuff..

So if I leave out a semi colon ie..

a + (b-a)*rand()

  %gives uniform random values in the interval [a,b]

c = (b+a)/2
  
  %calculating mean of values of mean between 1 and 2

((b-a)^2)/12

those commands are line by line and will just output a display? makes sense thanks..

[bio lim]

Yes, all of them will display their outputs on new lines. If I run your above program with (in this case it won't give any outputs since we ended it with semicolons):

a = 1;
b = 2;

My output in command window is:

ans =

      1.8147

c =

      1.5000

ans =

      0.0833

Also, if you don't define a variable when you are doing an operation, e.g., ((b-a)^2)/12, MATLAB names the output ans.
