I have a function f = y (x).
On the interval [a, b] I need to do a linear polynomial approximation of the data.
Linear means that the polynomial is of the first degree.
This means that it is described by two coefficients.
Those. I need to find two coefficients by which I can draw a red line like in the picture.
What MKL library functions can I do this?
You asked more or less the same question a month ago:
and the question was answered in that thread. In short, use the Lapack routine ?GELS.
Yes you are right. The problem is I can't figure out how to use the Lapack routine ?GELS.
I have my x and y data.
How do I use my data in
info = LAPACKE_dgels(APACK_ROW_MAJOR,'N',m,n,nrhs,*a,lda,*b,ldb);
And where will the result be? Where will the two coefficients be?
Glad to know that your issue is resolved. If you need any additional information, please submit a new question as this thread will no longer be monitored.
