Faster way to draw a solid circle
I need to draw a solid circle except the fill needs to be random weighted towards the center. I am currently doing the following: center = round(radius); cvs = zeros(2*center,2*center); cvs(center+1,center+1)=10^(color/10); for az=0:1/(2*radius):2*pi for r=1:center x=round(center+sin(az)*r); ... 13 Jul 2010 05:26

Irregular fourier matrix
I am doing some thing wrong here ! I am only concern with the spectrum... I have 750 samples My sampling rate is 4.00e^-10; f=-N/2:N/2-1 I am applying simple NDFT or Greg DFTGH ( As these lines are from greg code) on it Which is some thing like this....This is irregular signal not a regular one so taking real val... 13 Jul 2010 09:46

Matrix indexing with two arrays question
Say I have a matrix Test = [1,2,3,4; 5,6,7,8]; And two arrays corresponding to the rows and columns of points I'd like to set to zero in the matrix Test. Rows = [1,2]; Cols = [3, 1]; Is there any way to use a single line of code (I'm trying to avoid loops) to set the positions (1,3) and (2,1)... 12 Jul 2010 17:23

perturbation+for loop
Hi Friends, I have a matrix B of dimension (81x1541) and i'm adding +/-5% vertical perturbation to it as follows. a=1.05; b=0.95; C = [a*B(:,1:40),b*B(:,41:80),a*B(:,81:120),b*B(:,121:160),a*B(:,161:200),b*B(:,201:240),... a*B(:,241:280),b*B(:,281:320),a*B(:,321:360),b*B(:,361:400),a*B(:,401:440),... b*... 12 Jul 2010 16:15

Skip lines in an array -sorry
So I guess my real question isn't about for loops, but about passing in rows of data from an array of data into an array of zeros. If I have zero_array(min:max,:)=data_array(???) is there a way to skip every fourth row in five when passing the data into the new array? Maxx I'll be more pr... 12 Jul 2010 20:43
