Any function file contains a primary function that appears in the first line of the code. They are visible to functions in other files and can be called in the command line.
  2. That is correct, the variable current is acquired from a different script and it is located in the base workspace. My file is a function file and it only works if I physically copy and paste the variables into the file. I've never used assignin but I'll look into it and I hope this can solve the problem. Thanks!Read an indexed image into the workspace. imread uses two variables to store an indexed image in the workspace: one for the image and another for its associated colormap. imread always reads the colormap into a matrix of class double, even though the image array itself may be of class uint8 or uint16. I want a function to ask me the name of the variable from the base workspace to work on it. I have variables in the base workspace called A1, A2, A3. I want the function to read these variables into function by choice. I tried to assign the variables as global, however it doesn't seem to work.I have a user defined function in simulink. I need to use a global variable from simulink work space. How can access the simulink local worksspace, for the usage of simulink user defined function. Hi, Please find attached the simulink file.

Jun 30, 2016 · You can access variables in the base workspace directly from a script but not a function. To pass these variables to your objective function see http://www.mathworks.com/help/optim/ug/passing-extra-parameters.html. So you could change your function to using a script like this: % NLP - script x0 = ones(2, 1); f = @(a1b1)objfun(a1b1,x,y); [a1b1, sum1] = fmincon(@f, x0) And define your objective function in a separate function:

It reads data formatted in a format used by the model workspace. Use model workspace file types to move data to and from the model workspace to a function, an automated process, or a user interface.

We can find all kinds of weird functions inside MATLAB, I used it the first time inside a GUI, there's also the evalin function that you can use for similar purposes, it can even execute code on the workspace (good to define global variables on the workspace).Aesthetic quiz buzzfeedYou 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>
