Below is my 140*142 matrix. All odd columns (1,3,5…) are fixed code numbers for different systems. All even columns (2,4,6..) are time (durations) for each system. So for every value of an odd column (for example 1) there are 70 values. I want to remove all odd columns and just keep one column for fixed codes. and 70 columns for durations. My new matrix should be 140*72 shape. Any easy way to handle this problem in MATLAB?
