The Assignment Operator =• Typing x = 3 assigns the value 3 to the variable x.• We can then type x = x + 2. This assigns the value3 + 2 = 5 to x. But in algebra this implies that 0 = 2.• In algebra we can write x + 2 = 20, but in MATLAB wecannot.• In MATLAB the left side of the = operator must be asingle variable.• The right side must be a computable value.1-9More?
