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.
