Very useful video

Thanks a lot! You explain it very clearly and I like the notes for potential contexts to keep in mind

Nicely done. Thank you. A couple of comments to guide novice users who might see this video. In your "plotNice" function, I would set the font size of the title and axes separately or jointly using the set method on the GCA object. I had the impression that you caught this as you filmed the video. Also, when you talked about bugs in anonymous functions and how they might be difficult to troubleshoot, a simple example would have given a context to this idea. Thanks again for the video. Also, it's nice to see someone else who has invested a lot of time working with Matlab. :)

Yeah, good points for sure. I was debating refilming to fix the plot nice bug, but it wasn't really the point to get it exactly right, just sketch the idea. Plus I kinda like watching myself mess up. I definitely am running out of matlab stuff to talk about though, time to move on to bad mouthing python I guess :p

Very good video. I enjoyed the simplicity with which the function can be used. Nothing I hate more than having to configure plots on the fly while I use matlab.

Could you tell me please how to let the program' user enters a function and then the program deals with this function. For instance, when the user enters the function cos(x) the program calculates cos(2) . Also , when the user enters the function sin(x) the program calculates sin(2) and so on.

Do you want any function, or just specific ones? I talk about the general case in my eval video, although for the reasons I lay out there it is somewhat a dangerous approach. Please see if that video helps.

@@CodingLikeMad I need the user to enter any function and the program gives the value of func(2) for instance. I tried the inline command and it works. But I need not to use this command.

@CodingLikeMad 3 жыл бұрын

Yeah, the eval command will do that. See my comment from before.

@@CodingLikeMad Sorry to disturb you. But this is what I need. This is my code : f1 = input('Enter the function f(x): '); f = inline(f1); After that I can write in the command window: f(3) and I will have a result of substituting 3 in the function that the user entered. I would like to get red of inline command. How please ?

thanks. very helpful...But if I want to use a function handle with a variable number of inputs for example in an array, is that possible?

@alit8528 3 жыл бұрын

I want to define an objective function in which the number of inputs and their values changes in each iteration, so also inputs are not determined numbers

@CodingLikeMad 3 жыл бұрын

I would take a look at varargin, I dont know if it will work with function handles but that approach is a good start. You could also wrap the inputs in a structure and have equal number of inputs each time.
