How to translate command "GOTO" in fortran into Matlab
Hello all Matlab lovers: I meet some problem when I translate some fortran code into Matlab. In the fortran it is like this: ITER = 0; ...... (very long, around 2000 lines) ...... UMAX = ..... (100) if (UMAX <= 1e-7 or ITER >= 100) then LSTOP =TRUE ITER=ITER+1 GOTO 100 .... How can ... 22 Mar 2010 20:39

hydraulic valve modelling
I'm trying to model a proportional hydraulic valve with a pressure reducing and a pressure relieving action in Simulink or Simscape. Since this is quite a difficult task I was wondering if there were some people with more experience in this area.

Methods block: constructor doesn't find other method
Hello There, I've written a simple class in a classdefinition file. There are only two methods by now. The constructor and a function that should test if a condition is fullfilled for an instance of this class. The result is also saved in a property of that class. I want to call the helper method from the constructo... 22 Mar 2010 14:12

isfinite() of sparse -- cleverness needed
Greetings, I used to have this line of code: D(~isfinite(D)) = 0; However, as the size of D has grown, I've had to go to sparse D. As a result, isfinite(D) returns an out-of-memory error. I could do something like: D=sparse(N,M); % lots-of-stuff for a=1:N*M; if ~isfinite(D(a)) D(a)=0; end end ... 24 Mar 2010 07:42

fitting an integral function to a data set
Hi, does anyone have a good suggestion on how to fit any integral function in an smart way to a data set y? What is the best syntax to use? For example b / y(t) = | p*exp(1/2*(-v+V)/G^2)*t dv / a with the right hand side being an integral from a to b, and where V, ... 22 Mar 2010 13:04
