Replacing specific block with subsystems
显示 更早的评论
I want to replace all the 'Memoey ' blocks in a model with a subsystem which would have the functionality of 'Memory' block. But the initial condition to the 'Memory' block should be passed from From workspace block as the initial conditions are changed frequently. I have the initial conditions stored in an array. Any help is appreciated. I am using MATLAB 2020a

Here is one way. I think you would just use a constant block rather than From Workspace because From Workspace is looking to use a time sampled array or table, something like that.

See the MATLAB documentation on the block here for the types of data that the block can accept:
If you have data saved in the workspace that contains a scalar constant value that you want to use in this example subsystem or in Memory block, then copy that value into a new workspace variable and use that workspace variable in the Memory block, or in the constant block that I used here. The "Initial Condition" value must be a scalar value not a time series object.

After the first update, a memory block would make the output equal to input. This is what "initial condition" means. Or you may find that the Delay block is a better behavior, since it should be that output is delayed one step from the current input. You may experiment.
I do not know whether the From Workspace block can do what you want. Here is a link with more information.
