What info is needed? Solve in Matlab.

Write the MATLAB code that will compare the variables within the file named Lab4Prob4.mat and display one of two messages depending on the result. The two variables are named varA and varB. If varA is greater than vars, it should show the message "Variable A is greater than Variable B" on the command window. Otherwise, for all other cases, it should show the message "Variable B is greater than Variable A". Make sure that the messages are defined as strings called messageA and messageB. Display them using the disp() function
