multiframe dicomwrite
I have struggled with this same issue. After exploring the dicomwrite function a bit, it looks like the functionality is there for a multiframe dicomwrite, but its just not activated (at least as of my version which is R2008b). To get a multiframe write to a single file, I had to modify the private function dicom_enc... 21 May 2010 15:00

Joint Hypothesis
Hopefully I can explain my problem correctly. I am trying to find a way to conduct a joint hypothesis test in matlab. For example I want to test restrictions that equalize all regression coefficients of alpha, and then beta and then gamma of the following regression y(i,l) = alpha(l)*dummy(l) +beta(i,l)*A(i,l)+gam... 21 May 2010 15:00

Trimesh contour plot with nans
Hi, I am trying to display a contour plot using the trimesh function, but I have some nans in my contour vector. As expected, trimesh won't display the nan's but it makes the mesh elements with the nan vertex transparent. Here's example: x=[0 0 1 1 1]; y=[0 1 1 0 0]; z=[0 0 0 0 -1]; tri=[1 2 3; 1 3 4; 1 4 5]; ... 26 May 2010 12:27

Xls write cell array
Hi folks, is it true that xlswrite works with cell arrays? For me the following lines do not work, the critical range in the Excel sheet1 stays empty, whereas I get #N/A-s below which proves that ML writes something. a = { 'NA', 'NA', 'NA'}; b = [3, 2, 1]; c = { a; b}; xlswrite(xlsname,c,1,'A2:C5'); % ... 21 May 2010 17:13

2D gaussian fit of image
Logarithm-to-linear least squares methods can work quite well for determining the centroid and sigma of a 2-D Gaussian, including images where part of the Gaussian is masked out, when the Gaussian is floating in a sea of noise, e.g. an image of a star. The key is to remove the noise floor, leaving only pixels that a... 21 May 2010 13:53
