If you have a vector x = [1.92 , 0.05 , -2.43 , -0.02, 0.09, 0.85 , 0.06, -0.05, 0.3214, 25, 1 ,5 ,10 , 0.0125 , 100 ] do the following:
a. Replace any value between 1 and 4 with zero
b. Multiply any negative value with -1
c. Add 100 for the number that larger than or equal 5
d. Subtract 50 for the number that are smaller than 5

Hi,
You can look up to “Logical Indexing” section in the following documentation:
Matrix Indexing in MATLAB - MATLAB & Simulink (mathworks.com)
Try applying the same concept and try the questions then.
