Solution to system of equations
I would like to set up a generic solution to a system of equations that calls a function to return fluid properties for use in the solution. I have included the system below including the function call - refpropm. I had attempted to begin using a symbolic solution method but had been hung up on calling the refprop fu... 8 Jun 2010 17:11

hi, I am displaying multiple parameters on three different graphs from the same matlab program. Is there a way to show all these three graphs on separate graph windwos in one program run. I am not asking about the subplot option. thanks Erik ... 8 Jun 2010 16:01

Changing contrast of an background rgb image
I am displaying a color MR spectroscopy map image over a gray scale MRI image with transparency. To achieve this, I convert both images to RGB, using gray and color maps, and then merge them with required transparency. I want to adjust background image contrast giving specified window/level values. How can I achieve t... 9 Jun 2010 16:26

Problem sub arrays of diferrent sizes
Hi, I need your help in image processing in matlab. I have an image Rose size 256*256*3, an indexedRose size 256*256 and a paletteRose(RGB) size 4 * 3. I want to compute the mse (mean square error). Could you help me ? My code is [code] main.m [MseRose] = MseCompute(Rose,indexedRose); [/code] ... 8 Jun 2010 17:12

label each stem on a stem plot
Is there a way to label each stem on a stem plot? For example suppose the magnitude of each stem represented something, if I store what each magnitude represents, is there are way to output that on top of each stem in the plot? thanks ... 10 Jun 2010 14:32

Quick Question about Matlab
I paid $20 to get a CD with Matlab on it from my school assuming I could use the program whenever I needed. Now, when I try to use the activation key it says it is expired. It hasn't even been 1 year since I bought it. I didn't even need to buy MatLab but I thought it might be useful in the future. Did I waste my $20? ... 8 Jun 2010 17:12
