MATLAB: Matrix Manipulation in Simulink

matrix manipulationsimulinktable manipulation

Anyone here know how to edit data in a matlab 2D array (table).

I created a table using the xlsread command but now i want to write a function that can edit that array. I want to do this in simulink but can't seem to find a block that can do this.

Thanks for the useless answers.

I figured it out, there are two ways to edit a table. You can use embedded matlab function like this:

function y = WriteToArray(u,row,column,replacement); %#eml; u(row,column) = replacement; y = u;

or you can simply use the Assignment Block.

One approach (short version):

Add an annotation to your model, and write the command invoking your program in the annotation's properties' ClickFcn.

For more details, type

doc simulink.annotation

and look at the ClickFcn property.

(long version) Open your model, and double click anywhere on the background. This will add a annoation and a blinking cursor. Type in your annotation and hit escape to stop entering text. Right-click on the annotation and select Properties from the context menu. There is a text area (ClickFcn) to specify the commands to be executed when the annotation is clicked by a user.

You can use an annotation to comment and uncomment a block by enterting the code below as the 'ClickFcn' for the annotation.

if(strcmp(get_param(path_to_block,'Commented'),'on'))
    set_param(path_to_block,'Commented','off');
else
    set_param(path_to_block,'Commented','on');
end

Unfortunately, annotation properties can not be accessed programatically and hence, you will not be able to change the color of the annotation based on whether the block is commented or not.
