Question

How to write a for loop for the following window:
while (indx(end) <= numel(d)) && (tone_end_flag == 0)% index is the window that scans ands stops before d ends
x = d(indx);
[freqX magX] = goertz_max(x,Fs,20,22);
if magX>1e7 && tone_flag == 0
tone_flag = 1;
maxX = magX;
elseif magX>maxX
maxX = magX;
end
if (tone_flag == 1) && (magX < maxX/2)
tone_end_flag = 1;
tone_end = indx(1);
end
A = [A magX];
indx = indx + 1;
end

Answer 1

The second to last line, ind=ind+1, I need to change it into a for loop that will do the following:
Add 1 to indx if tone_end_found is 1
Add 5*Fs to indx if tone_end_found is 0.

Answer 2

This is in matlab.

Answer 3

A for loop is going to run for a certain amount of time, what are your conditions?

Answer 4

You might just put an if statement in to do what you want.

Answer 5

i meant an if statement

Answer 6

Sorry about the confusion.

Answer 7

is there such thing as an if loop?

Answer 8

No, it is a simple statement, if you want something to run but you don't know how long, you can usually put it into a while loop.

Answer 9

You want something like this?

if tone_end_found == 1
indx = indx+1;
elseif tone_end_found == 0
indx = indx + (5*Fs);
end

Answer 10

yes.

Answer 11

Kewl, well there ya go. :)

Answer 12

If I was to write it into this part of the code, will it be incorrect?
x = d(indx);
[freqX magX] = goertz_max(x,Fs,20,22);
if magX>1e7 && tone_flag == 0
tone_flag = 1;
maxX = magX;
elseif magX>maxX
maxX = magX;
end
if (tone_flag == 1) && (magX < maxX/2)
tone_end_flag = 1;
tone_end = indx(1);
end
A = [A magX];
indx = indx + 1;
if tone_end_found == 1
indx = indx+1;
elseif tone_end_found == 0
indx = indx + (5*Fs);
end
end

Answer 13

Starting around line 7 from the bottom.

Answer 14

I think it's good. Thank you!!
