How do you debug an error in MATLAB?

If you encounter run-time

run-time
In computer science, runtime, run time, or execution time is the final phase of a computer program’s life cycle, in which the code is being executed on the computer’s central processing unit (CPU) as machine code. In other words, “runtime” is the running phase of a program.

errors in your MATLAB® functions, the run-time stack appears in the MATLAB command window. Use the error message and stack information to learn more about the source of the error, and then either fix the issue or add error-handling

error-handling
In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program.

How does MATLAB calculate STD?

Description. S = std( A ) returns the standard deviation of the elements of A along the first array dimension whose size does not equal 1. By default, the standard deviation is normalized by N-1 , where N is the number of observations. If A is a vector of observations, then S is a scalar.
