Copy. function plot (x,y,varargin) Then inside this function, x takes the value of the first input, y takes the value of the second, and all the rest go into cells of the cell array varargin. So, in the last example, varargin would be a 1-by-6 cell array; varargin {1} would be the string 'Marker', varargin {4} would be the number 2, etc. MATLAB functions are generally defined input and output arguments. ... the function fun takes a variable number of input arguments with the help of the varargin ...A MATLAB function can take a variable number of input arguments, without the use of arrays or any additional functionality. The way to go about this in MATLAB is by using the varargin – which can be interpreted as VARiable ARGument INput. Now, the way to use varargin is in all lowercase and it must be passed as an input argument in the ...Description. varargin is an input variable in a function definition statement that enables the function to accept any number of input arguments.

A cell array is simply an array of those cells. It's somewhat confusing so let's make an analogy. A cell is like a bucket. You can throw anything you want into the bucket: a string, an integer, a double, an array, a structure, even another cell array. Now let's say you have an array of …func myFunc(varargin) if a not given as argument a = 2; if b not given as argument b = 2; if c not given as argument c = a+b; d = 2*c; end I want to call the above function once with b = 3 and another time while the previous one is running in the same command window with a = 3 and c = 3 and letting b take the default value in the function this ...Helper function for parsing varargin. Makes it easy to write functions that take arguments like this: subaxis (4,2,1,'spacing',0,'marginleft',.1,'H','pt',.1) ArgStruct=parseArgs (varargin,ArgStruct [,FlagtypeParams [,Aliases]]) * ArgStruct is the structure full of named arguments with default values. * Flagtype params is params that …2) Note that with this scheme, Matlab has no clever way of knowing which function argument fits into which option, so you must keep everything in sequential order. If you need more flexibility, you can do something sort of like keyword arguments by preceding the argument with a descriptive string, which is the way that some common functions ...

The program will run if I just use. someClass (filename, pathname) but I think I will have problems down the line when my number of inputs changes. This is code written by someone else. thanks.The most common ways of dealing with this are: Use nargin and some switch or if statements to detemrine the default parameters. Use varargin and logical indexing to detect non-specified arguments (e.g. empty). Use key-value pairs (usually with varargin) and strcmpi to detect the keys.Description. G = graph creates an empty undirected graph object, G, which has no nodes or edges. G = graph (A) creates a graph using a square, symmetric adjacency matrix, A. For logical adjacency matrices, the graph has no edge weights. For nonlogical adjacency matrices, the graph has edge weights.. Michael j fox imdb}
