I have a randomly generated vector, say A of length M. Say: A = rand(M,1) And I also have a function, X(k) = sin(2*pi*k). How would I find Y(k) which is summation of A(l)*X(k-l) as l goes from 0 to M? Assume any value of k... But the answer should be summation of all M+1 terms. ...
Does anyone know of a method to display a popup date selection calendar in a MATLAB gui? I know the financial toolbox has a uicalendar function, but unfortunately I don't have that toolbox. I have a hunch I'm going to have to use some Java or some other language for this one, which I know nothing about. I'm looking for something simila...

Hi, I have a set of points represented as a 2 row by n column matrix. These points make up a connected boundary or edge. I require a function that traces this contour from a start point P1 and stop at an end point P2. It also needs to be able trace the contour in a clockwise or anti-clockwise direction. I was wondering if this can be ac...

I am a little confused about the usage of cells and arrays in MATLAB and would like some clarification on a few points. Here are my observations: An array can dynamically adjust its own memory to allow for a dynamic number of elements, while cells seem to not act in the same way: a=[]; a=[a 1]; b={}; b={b 1}; Several elements can be ...
Hi I have a set of points which I want to propagate on to the edge of shape boundary defined by a binary image. The shape boundary is defined by a 1px wide white edge. I have the coordinates of these points stored in a 2 row by n column matrix. The shape forms a concave boundary with no holes within itself made of around 2500 points. ...
