How do I implement convolution of 3 functions in Matlab via FFT?

AI Thread Summary
To implement the convolution of three functions in MATLAB using FFT, the conv(u,v) function can be utilized for two vectors at a time. It's important to represent the vectors in complex form, using "j" for imaginary numbers. The process involves performing the convolution step-by-step, potentially using the FFT for efficiency. Users seeking assistance should ensure they understand the FFT implementation in MATLAB for optimal results. Properly structuring the input vectors is crucial for accurate convolution outcomes.

Hi, I need help about the convolution of 3 functions as shown in

attached file via FFT. Specially I need help about the Matlab

implementation of whole process.

Thanks in Advance.


Regards

In Matlab there is a conv(u,v) function where u and v are your vectors. I think you have to write the vectors in complex form (as in the form with imaginary numbers). Matlab uses "j" i think instead of "i"
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
