Jun 30, 2016 · And define your objective function in a separate function: function sum1 = objfun(a1b1, x, y) sum1 = sum(abs(a1b1(1) * x + a1b1(2) - y)); An other alternative would be to save the base workspace to a file and load this file in your main function. In this case you could update your function like this:

07.03.2013 · When my function returns to the commandline, the output variables from the function do not appear in the Workspace terminal. When I call "Who", they are listed there. When I try to open a variable (any variable) in the command line, the program sits "busy" for several minutes until I get fed up with waiting for Matlab to print the variable output and terminate the …

Jun 27, 2009 · The EVALIN function allows you to evaluate commands in two specfied workspaces: 'base' (MATLAB's base workspace), and 'caller' (the workspace where the function was called from). In the case where the function was called from the base workspace, the two workspaces are the same. You will need to create a string that will evaluate as the proper ...

Apr 08, 2014 · You can use evalin to work with variables from another workspace. In your example this could be. T = evalin ('caller','length (data)') But please note that in most cases you get cleaner code if you define the variable as input argument for the function. So for your case this would be.

26.02.2014 · I'm a total beginner to Matlab so would really appreciate any tips. I have a one-output function F, which creates various transitional variables while processing. For example: F=myfun (x1, x2, x3) a=f (x1) b=g (x2) F=z (a,b,x1,x2,x3) end. I wish to have these transitional variables a and b available for viewing and editing in the workspace ...

The base workspace stores variables that you create at the command line. This includes any variables that scripts create, assuming that you run the script from the command line or from the Editor. Variables in the base workspace exist until you clear them or end your MATLAB ® session. Functions do not use the base workspace.

Local variables are not available at the command line or to any other function. However, there are several ways to share data between functions or workspaces. Best Practice: Passing Arguments. The most secure way to extend the scope of a function variable is to use function input and output arguments, which allow you to pass values of variables ...

I used to always start MATLAB code with 'function' and used to have the same name for the file. Theme.

Workspace, Variables, and Functions in MATLAB Workspace. The workspace contains all variables we create while working in MATLAB. Whenever we assign a value to a variable, it automatically gets space in the workspace. Workspace variables lose their existence after the closing of the environment, so save these variables in a file to use later on.

MATLAB ® initializes persistent variables to an empty matrix, []. For example, define a function in a file named findSum.m that initializes a sum to 0, and then adds to the value on each iteration. function findSum (inputvalue) persistent SUM_X if isempty (SUM_X) SUM_X = 0; end SUM_X = SUM_X + inputvalue; When you call the function, the value ...
