using sinc to smooth a function
Hello, I'm trying to take the fourier transform of a shifted rect function. It appears that Matlab is connecting my samples in straight lines, and I want them smoothed out to be a curve. I know you can use the sinc function to do this, I'm just not sure how. Here's what I have so far: x = linspace (-5,5,5001); x ... 27 Mar 2010 01:09

A problem with IFFT
Hi, I have some problem with IFFT in MATLAB. First i have a vector frequency f, and a vector for corresponding spectrum XF. XF is calculated with a Mathematic expression. The size of this vectors is very long. So i reduce it by using : f=f(1:3:end); and i do the same thing for XF. This is to reduce time computation us... 26 Mar 2010 22:53

passing MATLAB structures to C/C++
I am rewriting a function which was previously implemented in MATLAB as a mex function for speed. The original function took a structure as an input and returned a structure as an output. Is there a way to pass a structure directly to a mex file, or perhaps a way to generate a C/C++ struct from a MATLAB structure? ... 29 Mar 2010 11:20

tiled texture mapping
I have a 128x128 tile-able image that I'd like to tile over a rectangular object defined by 'bounds'. I figured out that if I just want one image, I can say texture = imread('texture128x128.jpg'); npoints = 128; [XX YY] = meshgrid(linspace(bounds(1),bounds(2),npoints),linspace(bounds(3),bounds(4),npoints)); ZZ = ... 26 Mar 2010 21:40

Significant Figures
Hi, If I have a value of 22.223 and 1.342 , how can I get a result like 22 and 1 only? I need to eliminate the numbers behind the point and get a whole number instead. my implimentation is this: x=2250 x1=x/1000 x1 will have a value of 2.250, and I want to get a value of 2.000 instead. x2=x/100... 26 Mar 2010 19:11

Memory Leak loading many *.mat files.
I have a similar problem. I run a script that sequentially loads, modifies, saves, and clears large struct arrays from *.mat files that are ~100 MB each. MATLAB steadily increases its memory use until the computer hangs, even though total size of the variables in the workspace remains bounded. I would like to know how ... 26 Mar 2010 17:54

Issues with resizing subplots: limits to maximum subplot size?
I'd like to create a 1x4 subplot where figures are spaced evenly. To do this I expected to execute a simple script like the following: clear all x=-1:0.1:1; for n=1:4 h(n)=subplot(1,4,n); plot(x,x.^n) set(h(n),'units','points','position',[100*n 50 50 50]) end which makes the four subplo... 26 Mar 2010 19:11
