Interpolation over triangulation
Hi there, I have 2D piecewise linear data over a triangulation given. From this data, I'd like to obtain an interpolation with (piecewise) polynomials of higher order (doesn't necessarily need to be polynomials). So it should look smoother. (Looks is not the main goal, but a side effect). To get my point over bet... 29 Jul 2010 16:17

Help with bootstrapping
My question: I would like to know if there is a way to use the function polyfit in a bootstrap analysis. My data: X = 36.06 45.12 31.43 34.31 14.75 24.40 24.75 24.75 24.65 24.63 Y = 150.91 199.90 145.15 147.21 91.241 127.44 128.01 125.02 131.6 124.93 My first attempt: [poly,err]=bootstrp(1,'... 30 Jul 2010 10:46

Axis Image and positioning
How can I do "axis image" and still have the cropped axes appear at the same width and height as the original axes? I don't want them to shrink. When I do "axis image", it crops the empty space off of my pcolor plot. That is good. The bad part is that the axis "Position" property doesn't change. I'm trying to do a... 29 Jul 2010 16:17

mex error
Hi, I'm attempting to use a mex-file that has apparently been validated on the two versions of Matlab I use (2007a and 2010a). However, when I run it, I get the error listed below. (Similar in 2010a.) I don't have the mex c code, so can't recompile. Is there anything else I can try to diagnose this? Both copies are s... 29 Jul 2010 16:17

finding solution to 2 equations of 2 variables, not explicit
Hi I have 2 functions that are very complicated functions of x and T. I produced some data and used TriScatteredInterp to generate 2 functions F1 and F2 for each function. Now I would like to find x and T such that F1(x,T)=A and F2(x,T)=B for a given [A,B]. Since F1 and F2 are not explicit functions I can't direct... 29 Jul 2010 21:47

Displaying Only Last Positive Value
Hi, Im trying to figure out a way to display a "range" for the given function below. However, the number I would like to display as the "range" of this function should only be the last positive value along the x axis. Any insight is apperciated. % trajectory: function to solve trajectory motion with inputs of ... 29 Jul 2010 15:11

Save and control figure size with print
I'm trying to write a script that saves a figure in png format. My figures are best viewed when stretched side-way, so I want the saved figures to be of the size 8 inches (height) and 16 inches (width). How do I do that with the print function ? If you could give me an example, that would be great. ... 31 Jul 2010 21:37

Ignoring certain rows
Hi i have proceeded as follows, matching a timeList to minutes of the days; tmpIdx = find(timeList == thisMinuteOfDay); should return (in tmpIdx) the element of timeList that corresponds to this particular minute of the day. . Note that sometimes tmpIdx will be empty as the minute of day for the current observa... 29 Jul 2010 16:17

Weird OOP memory usage
Caveat: I am very new to OOP, both in MATLAB and in general. I've been seeing some weird memory usage. For example: % saved as myClass.m classdef myClass properties prop1 = 0; prop2 = 0; prop3 = []; prop4 = []; prop5 = 0; end end % at the command line... 29 Jul 2010 17:23
