how to solve *out of memory* error
Hi guys, I just started to use matlab. I got the *out of memory* error while I used the following commands: load out.txt [X,Y]=meshgrid(out(:,1),out(:,2)); Z=griddata(out(:,1),out(:,2),out(:,3),X,Y); surf(X,Y,Z); the out.txt is smaller than 300kb. And I am pretty sure that the memory available is big enough. ... 25 May 2010 02:39

Program works fine in debug mode but not in automatic run
Hi all, I was trying to grab blocks of data from a large image. I am grabbing blocks of 510 x 1000 and trying to extract information from each block. The block is grabbed by taking a snapshot using an .OCX functionality. ( this is for a specific project, so I cannot provide the vendor names and stuff ). In the a... 26 May 2010 12:27

Renderer: Painters. export_fig
Hello, I am writing in the hope that someone in the Matlab-community might be able to help me with the following issue: I am using the surf-plot command to plot a three dimensional plot, and I then rotate the plot via view(2), such that it is view from the top down. Since I am using labels with the ('Interpreter',... 24 May 2010 16:48

Using ginput or related fuction to "connect the dots"
I have a problem that is really important to all my work. If I were to design, say, a space truss in three dimensions, the smallest number of inputs would be the coordinates of the nodes. I would like to then plot these nodes in two or three dimensions, depending on which allows for the most clarity, and specify the... 25 May 2010 12:25

Save figure as 1 bit tif
I would like to save a figure window as a one bit tif file. print -dtiff saves a 24 bit tiff. I can read the tiff back into MATLAB easy enough. How do I convert it to 1 bit tiff and resave it? I have been around MATLAB for almost 30 years, but I am not a image processing person. I do not have the image processing toolb... 25 May 2010 08:00

Non-Linear Frequency Response
Hi! I have a simple system, for the input I know the fft and for the system I know how the frequency response, the problem is that the response is no linear, it represents the bahaviour of an electrical circuit, the complication is that the circuit paramenters vary with the frequency. So I think that just a multiplicat... 24 May 2010 15:41

Importing data from Excel using xlsread
I am attempting to import some data from Excel using xlsread. Everything is working fine except in one particular case. Every now and then it'll come across a cell whose value is too long and it will import a NaN. When Excel is opened ###### is displayed. However, when you click on the cell the value is there. Also, if... 26 May 2010 12:27

64bit compiler selection
Hi, I'm struggling to install 64bit compiler to my laptop (Windows 7 64bit). My MATLAB is 64bit, and I tried to follow the direction from mathwork. So, I installed VC++ 2008 express and SDK version 7.1. Then, I tried to run mex -setup. It only can show visual studio 2008 express in 32bit direction (Program Files (x86... 24 May 2010 13:27
