power density spectrum by c programming

[arda]

does someone know that ANSI C has a power density function or not? if not how can i achieve to do it ? or is there anyplace that i can find some info about it

[RADAR]

i don't think so mate.Although it does not include any type of mathematical functions(user defined),i guess you can do it with defining a function.Likewi se the fahrenheit and celcius conversion, you can define the arithmetic calculations in a function named power_density_s pectrum
I hope i could help you with that situation.But due to my lack of physics knowledge I couldn't explain how to graph them.I guess you are somewhere from Europe(TURKEY?) .We may argue about those maybe on our e-mail adresses.If you want to contact write an answer under that topic.
Respects,

C doesn't have that capability.

You could write your own power_density_s pectrum function/sub-routine/ class using an algorithm obtained from "Numerical Recipes in C" (google the title and you will find a link to a free copy of it)

Or you could use the capabilities of a program like Mathematica or Matlab.
These programs already have the power_density_s pectrum algorithms encoded, you just have to know how to call them.

yes i am from TURKEY,but how you understood this? Have you been in TURKEY or you are also Turkish which is the minimum probability:)? i have a project and in this project i have 3 output values. These are snr,BER(bit error probability) and number of errors respectively. By these outputs i have to draw power density spectrum but i have no idea how to do it
