turn a 2d matrix into 3 arrays
Helo! I have a matrix G(n,m) and I need to be able to convert it to a dxf file. I am having trouble extrapolating the values in the matrix and turning them into 3 matrices for each dimension x,y,z. I want the value in the matrix to be dimension z and the rows/columns to be x and y respectively. basically, I want ... 1 Jul 2010 13:20

variable declaration
Hello everyone! I have encountered some problems in an embedded function block. I have tried many ways to declare the output variables, but I couldn't make it. Below you can see my code: function [d, phi_seg,Break]=seg(D,PHI_seg,index,D_size) % d=eml.nullcopy(zeros(1,D_size)); % eml.varsize('d') if index == ... 1 Jul 2010 01:17

ignore output arguments of a function
Let's say that I have a function myFun with multiple output arguments. function [A,B,C,D,E,F] = myFun(inputArg) .... end I want to have only the last argument of the output arguments without actually assigning the rest of the arguments. Nowadays I just use the following: [dummy, dummy, dummy, dummy, dummy,... 30 Jun 2010 19:48

Changing The Polar Axis Values
Hello, I am plotting a polar chart of the edge of a pipe. I am plotting out the deformation from the pipe's original location. On the chart there are different shaped rings showing different deformation at different times during the test. Is there a way to make the center of the polar chart be negative? I want to s... 5 Jul 2010 09:57

Concat string to cell array of strings
Hi, I'm trying to concat a string to each string in a cell array of strings using: first = 'first_' attach = { 'end' 'end1' 'end31' } i=1:1:size(attach,2) cellfun( @(x) [first x(i) ], attach, 'UniformOutput',false) It works, except that all of the values in attach are truncated to 'end'. How do I prevent ... 30 Jun 2010 15:21

writing values into excel column wise
Hi, I tried to write into an excel file a series of values.They have to be in such a way that set1 values are in first column,set2 values in second column and so on.So that I can make calculations easily(which is my intention).But the result is with bad alignment. Could any one suggest me how to do this. Anoth... 30 Jun 2010 16:28

Correctly passing/using variable in sub-level of Simulink model?
I believe that this is a straightforward question, but I haven’t been able to discover the solution by looking at the Mathworks documentation ('Inport' block info): I have a Simulink model “my_model” that contains a block (sub-level) named “Joint Angles”, which contains a bunch of bloc... 30 Jun 2010 17:35

UITree Refresh without collapsing
Look at the reloadNode method for the tree. If you "reload" the parent level, then only the parent collapses, but you can keep the path and expand it back. "Chris Ford" <chris.ford.vsi(a)gmail.com> wrote in message <hovvi3$hpf$1(a)fred.mathworks.com>... Hi, I have implemented a uitree in a GUI but am having a... 30 Jun 2010 14:14

Problems with fmincon when trying to compute transition probabilities
Hi all, I keep encountering a problem with fmincon when I use it to solve Markov transition probability matrices. I have no inequality constraints in my program, just boxed constraints, namely that the resulting answers are probabilities, therefore there is an upper bound of 1 and a lower bound of 0 on my variables... 30 Jun 2010 14:14
