scalar double problem with shapewrite
I continued to be puzzled with this problem of trying to convert a matrix using the shapewrite function. I have the following matrix... A = [1,2,3,4]; lon = [-123.412482300000, -123.349197000000, -123.387645500000,-123.499196100000]; lat = [48.1177411000000,48.1170438000000,48.1850616000000,48.2661300000000]; [t... 9 Mar 2010 14:38

hist3 returning indices
Does anyone know, is there a way to call hist3 (or something similar) to conduct a 3D histogram on a matrix of data, but to also return a matrix of indices specifying which bin each of the data points were placed? I know I can do this manually with histc functions, but it's cumbersome. Thanks, Val ... 10 Mar 2010 16:26

Changing Axis Tick Font
I am having difficulty changing the font for the ticks on a subplot axis. I am able to change the font size fine, but the font itself, and the legend font, do not update as the axis labels do. Here is part of .m script: legend_h=gca; set(legend_h,'FontSize',6,'FontName','Courier'); subplot(4,1,2,legend_h... 9 Mar 2010 14:38

reshape
The values are not like this. They are x,y,z coordinates which looks like a nonuniform shape (has no pattern). It is like a grid. The rows are the different position of that grid in the depth. Another problem is how I can connect the xyz coordinates together to form a grid looking shape if the data is not structured in... 9 Mar 2010 13:29

R^2 greater than 1 in regress output?
I am using the regress function to do linear fits of a number of three-dimensional data sets (two regressors and one observation) and seem to be getting R^2 values greater than 1 for some of the sets. From the info in Matlab's help, I get the impression that the first element in the "stats" vector that regress outputs... 9 Mar 2010 18:05

Passing data between functions in a GUI
hI, New to GUI development, managed to obtain this really simple GUI example but I sd not understand the following line: S = varargin{3}; % Get the structure. Why is it varargin{3}????? and not varargin{1} or 2 or 4 etc Thanks CF and the main code is: function [] = GUI_3() % Demonstrate how to hide a... 10 Mar 2010 10:47

If/then subsystems - I'm missing a subtle point
Hello, I am developing a model that activiates certain subsystems when a time condition has been met. What I am observing is that once the 2nd block of "if/then" subsystem becomes "true" it continues to operate even if the 1st block of the if/then subsystem condition is no longer met. I've selected the "reset... 11 Mar 2010 11:08
