contour plot Hi, I'm trying to get a contour plot of the following function [q,p] = meshgrid(-1:0.1:1); H = q.*p.^2; contour(q,p,H); The result is shown here: http://www.maikelbosschaert.nl/math/contour_H.jpg The problem is that the zero level set is wrong. I'm missing the right line when H=0: (q,p)=(q,0) with q \in... 17 Apr 2010 09:40
printing data from a cell array to a file Hi, I have a cell array full of data so that when I type this array name in the matlab terminal you get: K>> my_data my_data = Columns 1 through 7 [17x1 char] [17x1 char] [18x1 char] [18x1 char] [18x1 char] [18x1 char] [17x1 char] [17x1 char] [17x1 char] [18x1 char] [... 17 Apr 2010 09:39
dialysis project using simscape Hello everyone, i'm a final year student working on a portable dialysis machine. to be more specific i'm working in a simulation of this projedt and i've found out that the best simulation program is MatLab. to simulate my machine i need to know the blood and the dialysate- the liquid that is used for cleasning... 17 Apr 2010 08:33
Averaging linear and cubic interpolated values Rune Allnor <allnor(a)tele.ntnu.no> wrote in message <f62fa091-7aef-477a-806b-974544c0bba4(a)r18g2000yqd.googlegroups.com>... Splines produce very smooth interpolating curves, but require all the data to be available and are computationally expensive. The "require all the data to be available" part is simpl... 17 Apr 2010 10:45
Cannot open "mclmcr.h" "david park" <dalgoozirang(a)naver.com> wrote in message <ff4oos$e7e$1(a)fred.mathworks.com>... I made a standalone executable file named 'left.exe' surely when I double click this file it is well executed. Additionally other files were created including 'left.c' So I implented visual studio 6.0 to open '... 17 Apr 2010 07:28
trim functions or relevant function i have a function in m file. it uses inputs and calculates outputs for a control system. normally for mdl files, i use "trim" function to linearize my models. but i think trim can't be used for m files? what would you propose? Thanks in advance. ... 17 Apr 2010 08:33
speed up fwrite Hi All, I need to create lots of files, which I subsequently need to open, do some calculations and save back. Essentially I would like to improve the speed of the following for loop: clear all tstart = tic; N = 100000; P = 10000; for k = 1 : P vecID = k; % calc out = rand(N,1); % output file... 17 Apr 2010 12:59
norn-constrained portfolio optimization Hello, i am trying to solve norm-constrained minimum variance portfolio optimization using fmincon function, but haven't figured out how i put the norm constraint into function. my objective function is: min(w) w'*C*w s.t sum(w)=1 sum of abs(w)<=c so here is my question, how put the 'sum of abs(w)' ... 17 Apr 2010 07:28
