Boolean numbers are either "TRUE" or "FALSE", represented in MATLAB by a 1 and a 0 respectively. Boolean variables in MATLAB are actually interchangable with doubles, in that boolean operators can be performed with arrays of doubles and vice versa. Any non-zero number in this case is considered "TRUE". Most of the rational operators …There are different ways to print outputs in the command window in Matlab. We can use the fprintf() or disp() methods. Use the disp() Method to Print Output in Command Window in Matlab. The disp() method displays the value of a variable in Matlab.
