Your first task is implementing a function that computes the rms value of a signal $($vector$)$ using the above mentioned formula.

a$.$ You will have one input argument and one output argument.

i$.$ The input argument is a vector of any length. The output argument is the rms value of the vector.

b$.$ You are only allowed to use the Matlab built$-$in functions: length, size, and sqrt in your function. You can also use if$,$ elseif, for or while $($if required$).$ You should not use the built$-$in matlab function $\text{'}$rms$$ to compute the RMS value in your code. You can, however, use the $$rms$$ function to check if your implementation is working correctly after you are done writing your function.
