Answer 1

[Sean de Wolski]

What do you mean by "calling out"? Extract, replace, display etc?

Typically, when I think "calling out", I think either getting a free day off work or letting someone know they're lying to me. E.g:

• Me: Do you want to go bar?
• Friend: No, I have homework to do.
• Me: Yeah right, you haven't done homework in a year, especially not on a Sunday during a football game!

to display or extract 3 from t above:

t13 = t(1,3)

Answer 2

[Robert Cumming]

do you mean

value = t(1,3);

.... if so you should look at:

Answer 3

[Deep Kotak]

Just you have to take some variable to store its value

x=t(1,3)

x=3

even if you want to replace that value with some another value then you need to write

e.g.

t(1,3)=5

then t=[1 2 5 ; 4 5 6 ; 7 8 9]
