Setting origin position
I am trying to do what seems like a fairly simple task (and it probably is!!!) I want to plot F1 = [594 651 705 680 668 640 620 582 580 531 480 422 331]; F2 = [913 921 1105 1220 1265 1334 1296 1242 1204 1112 1028 951 814]; as plot(F2,F1) The only thing is I need the origin to be in the top right corner with the ... 15 Apr 2010 08:03

Convert vector of double to string?
I need to convert the double elements in a vector to string elements. I have tried: v = [23 12 34 34 12]; v_str0 = num2mstr(v); v_str0(1) ans = [ v_str1 = num2str(v); v_str1(1); ans = 2 what I want is: v_str1(1); ans = 23 How do I convert all digits for each element into stri... 14 Apr 2010 20:03

Help with Mexnc define variable
I'm trying to write a new variable to an existing netcdf file using existing dimensions. I open and put the netcdf file in define mode; then I: status=mexnc('def_var',ncidg,'region_mask','double',2,[dimid_xi_rho dimid_eta_rho]) where dimid_xi_rho=2 and dimid_eta_rho=1 -OR- status=mexnc('def_var',ncidg,'region_... 14 Apr 2010 20:03

Hi, Is there an efficient method or builtin function that will fan out data columns in my matrix? For example, if I start with an unknown data matrix, M, I'd like to get N in an efficien... 14 Apr 2010 18:55

Reading dynamic variable names in a loop
I'm writing a GUI with guide and it has 7 pop-up windows for the user to enter information depending on the product. They only fill out one of the seven pop-ups. Each pop-up menu has 20-25 edit boxes and I'm using setappdata and getappdata to transfer the information back to my main program. My question is, is ther... 14 Apr 2010 18:55

Setting image data using spatial coordinates
Let's say I have an image; A = imread('peppers.png'); This gives me an uint8 RGB image. Now instead of using the pixel coordinate system to access the pixel A(1,3), I would like to set the pixel values using spatial coordinate system: A(2.9, 1.3 :) = [255 255 255]; This obviously gives me an error expecting a... 14 Apr 2010 18:55

Global Fit
Hi, I am new to this and hope you can help. Situation is that i have 4 simulated curves that is supposed to describe 4 measured data. there is a scaling factor to convert the calculated into the measured. I want to globally fit this scaling factor. So where is the problem? the thing is, so far what i have been ... 14 Apr 2010 18:55

repmat without tiling?
Hi, Is there an efficient method or builtin function that will fan out data columns in my matrix? For example, if I start with an unknown data matrix, M, I'd like to get N in an efficient way than for loops. M = ones(5,1)*(1:3) N = fanout(M,3) where, N should equal: N = ones(5,1)*[1 1 1 2 2 2 3 3 3] ... 14 Apr 2010 17:47
