error using lsqcurvefit function
I am trying to use the lsqcurvefit function as such: M.file - "Phenocam" xdata = [0.9 1.5 13.8 19.8 24.1 28.2 35.2 60.3 74.6 81.3]; ydata = [455.2 428.6 124.1 67.3 43.2 28.1 13.1 -0.4 -1.3 -1.5]; x0 = [100; -1]; % Starting guess [x,resnorm] = lsqcurvefit(@my_fun_Phenocam,x0,xdata,ydata); M.file - "my_fun_Phen... 9 Jun 2010 17:34

How can I automate a script asking for terminal input?
I have a script that asks for user input via a call to the "input" function. I would like to to programmatically supply this input when the script is called. While it would be simple to modify the script, I would like to avoid changing because it is a third party script that frequently changes. The way it is used d... 10 Jun 2010 08:52

OpenGL performance
I have a very general & naive question about OpenGL's performance in Matlab. My subjective impression is that OpenGL under Matlab doesn't deliver the eye popping capabilities that seems to with other programs that also claim to use OpenGL for video (specifically 3D stuff). I realize I'm being very general & waving ... 9 Jun 2010 17:34

DAQ getting less than samplerate. Why?
I am using a Data Translation board to capture data. I want to capture data at 200Hz, but I am ending up with 140 samples/second. My design is calling a timer every half second. I query the adaptor to see if data is available. For whatever reason, it seems to be available whenever 1000 samples are captured. That... 15 Jun 2010 09:47

Unexplainable Mex Error
I've been working on some C++ code for awhile that interfaces with MATLAB through Mex. I get a segmentation fault 90% of the time when I run the code (with the exact same inputs), but the stack trace with gdb tells me extremely little in terms of what's going on. I've even added mexPrintf statements to try to figure ... 9 Jun 2010 17:34

for loop imread
I would like to read in a series of images with imread, but do not know how to do it. The filenames for the images are of the format 1A.tif, 2A.tif, 3A.tif, etc. so to read in one file imread('1A.tif'); and to loop the names of these files for i = 1:n eval([num2str(i),'A.tif']); end but when I combine the... 10 Jun 2010 00:12

txt data manipulation - save data from one complex txt file into separate txt files
Dear All I need to save the data between the line "#L strech-h H K L ..." and the line '#c' into separate files. This file below has two blocks of such data and therefore needs to be saved in to two txt files. The original data has lot more blocks.

Rotate histogram
Hi, I'm wanting to rotate several histograms 90 degrees clockwise, and put them sequentially along the X axis. I haven't quite understood how to do this from reading the posts on the forum. If anyone would be able to give me direction that would be great. Here is a picture I sketched of what I want to accomplish: ... 9 Jun 2010 16:26
