The equal sign, equals sign, or "" is a mathematical symbol used to indicate equality. It looks like two parallel horizontal lines. The equals sign is placed between the things stated to be exactly equal or the same. Learn foundational programming concepts (e.g functions, for loops, conditional statements) and how to solve problems like aIt declares a variable called z, but the right hand side of the equal sign has.particular, the box named on the left side of the equal sign. Here were going to do x z-1, so. Since the equal sign is the assignment operator, and does not mean equality, the statement should be read as mynum gets the value of 6 (not mynum equals 6).In this chapter, we will introduce the simplest MATLAB programs, called scripts.
