The manual contains a number of code examples to demonstrate both some particular features of the small matrix functions and how these functions can be called.
Many of these code examples output result data together with status code and associated messages in case when error condition was met.
To keep the example code simpler, special definitions of print statements are used for better representation of results, as well as print status codes and messages.
The code definitions given below make it possible to build the examples contained in the manual by straightforward copying and pasting the example code fragments.
/*
// The functions providing simple output of the result
// for single precision and double precision real data.
// These functions are only for tight data:
// Stride2 = sizeof(dataType)
// Srtide1 = width*sizeof(dataType)
// Stride0 = length*sizeof(dataType) - for vector array
// Stride0 = width*height*sizeof(dataType) - for matrix array
