Confirm my understanding..
- You have a variable in the workspace with 5 columns and n rows
- You want to provide individual column vectors of this variable as inputs to signals using from workspace blocks
is that right?

See the implementation (attached) of the From Workspace blocks to split the matrix

thanks for your help.. I just tried it I got two types of error that
Error evaluating parameter 'VariableName' in 'From Workspace'
and
Undefined function or variable "a".
actually (t) and (a) refer for what?

e.g.
a = [1,2,3,4,5;6,7,8,9,10];
t = [0;1];
& do the necessary solver settings for two time steps for this test example
