Making new waves

Fri, 10/04/2013 - 09:45 am

I would like to write a procedure to create a specified number of new waves. I want the waves to have the name funct plus a number. I want the number to increase systematically. Here is what I have, but I don't know how to fix the name of the wave generated.

Function GW(Int, j)
wave Int//This is the intensity wave. I want to mimic its length
variable j//this is the number of waves I want to generate
wavestats Int//I do wavestats to determine the number of points in the int wave
variable i//This is the loop variable
i = 0
do//loop declaration
i+=1//increment the loop variable by 1
make/c/n=(V_npnts) func//make a wave called function that has the same number of points as the int wave.
while (i < j)
end

How do I make the funt wave have the following names for j = 3. Funt1, Funt2, Funt3?

Function GW(Int, numWaves)

    wave Int        //This is the intensity wave. I want to mimic its length

    variable numWaves       //this is the number of waves I want to generate

    variable i      //This is the loop variable

    i = 0

    for (i = 0; i < numWaves; i += 1)       //loop declaration

        Duplicate/O Int, $("func"+num2str(i))       //make a wave called function that has the same number of points as the int wave.

    endfor

end

As a matter of style, its bad form to call in input parameter "j". All variables, especially input parameters, should be named descriptively. It makes it much easier to read the code months later when you've forgotten why you wrote it in a particular way.

The key here is the $ operator that takes a string expression and tells Igor that the string contains a name.
