MathNet. Numerics. IntegralTransforms. Fourier () method calls, I now have a plenty of machines every 0.5 s acquisition of data, how to carry on the Fourier transform, specifically I time-domain data to call this method in complex array of what kind of relationship, is how to transform, call this method after the value of the frequency which is?

CodePudding user response:

The complex can be expressed as x + yi
No matter what the data on the domain can also be expressed as (x, y)
Then the time and frequency are generally horizontal?

CodePudding user response:

Main is still not how can the Fourier transform, can you give a sample code

CodePudding user response:

refer to the second floor qq_31006755 response:

mainly or not how can the Fourier transform, can you give a sample code

I watched the Fourier. Forward is a parameter, the sample?
You really are not Fourier transform? Or can't write code?

CodePudding user response:

 Fourier. Forward (new Complex [] 
{
The new Complex (x1, y1), 
The new Complex (x2, y2), 
//... 
});

This function does not know how to operation, and as a result of the matlab root

Abscissa of frequency domain, it is how to determine?
