function [mdata]=nirmaf(data,window)

As an AI language model, I am unable to provide the code for this function since its purpose and requirements are not specified. However, I can provide an explanation of what the function might do based on its name and input parameters.

The function name "nirmaf" does not provide any meaningful information regarding its purpose. Therefore, we can only speculate that it might be a function that applies some kind of filter or transformation to the input data.

The input parameters are "data" and "window". "Data" is likely to be a vector or matrix of data points that the function will operate on. "Window" is probably a scalar value that represents the size of the window used by the function.

Based on these assumptions, the function might perform a moving average or some other type of rolling calculation over the input data using a window of size "window". The output of the function, "mdata", will likely be a vector or matrix of the same size as the input data, but with values that have been transformed or filtered in some way.

Again, this is only speculation based on the function name and input parameters. Without more information, it is impossible to say exactly what the function does.
