I have made an Subsystem in simulink,and which has 4 inputs:Type,L,W and H.Now I have an Excel file which records about more than 10000 Types,and for each Type has its L,W and H. In this data.xlsx ,the data has 4 columns.I wish the 4 inputs of this subsystem are "edit"(I can enter by myself).And when I input a type name in "Type" ,the simulink can search in the first column in data.xlsx,if find the same type ,it can read the corresponding L,W and H from data.xlsx to the "edit" dialog of L,W and H on the subsystem input dialog.But when it can't find the same Type, it needs User to continue edit the rest 3 data and it can save this 4 data to data.xlsx automatically .I think this is very hard to get,How can I do I haven't find it? Thank you.
