The inline function is not recommended. If you were writing a function to be evaluated in MATLAB, you should create an anonymous function (either by typing it explicitly or using str2func.) But since you want to create a symbolic object use the str2sym ...

Only one public function can exist in a MEX interface module. In this case, it is svflow(). This function is how MATLAB scripts call into the MEX module. The name of the function is arbitrary, but 'svflow' was chosen as the moniker for the overall host/target protocol as ...
Abrir en MATLAB Online You can also use the 'all' function: ThemeCopy sum(all(diff(a,1,2)==0)) 1 comentario Rik el 9 de En. de 2018 It might not matter at all, but I would like to point out that this is about twice as fast as my answer (at least on my machine on ...

Ciuban, if you want every combination, it sounds like you want to calculate the inter-point distance matrix. This can get very memory-intensive if done poorly/naively, so I'd recommend using one of the File Exchange solutions for this. I'd recommend:編...
We need to know: are the "u" values symbolic or numeric? If they are symbolic then diff(c3,t) makes sense in itself, but each "gu" will be symbolic when generated. If the "u" values are numeric, then diff(c3,t) is going to ask for the "t'th" numeric difference, and since ...
In my understanding, the finite difference derivatives at initial point shouldn't be effected by using parallel or not? I do not really know how to solve this problem. I tried to use diff function to find an initial point where the derivative is...
