Equal
Generates the Scilab internal code representing an instruction "LHS = RHS"
Syntax
eq = Equal(lhslist, RHS)
Arguments
- lhslist
list of Left Hand Side parameters (list of "M2SCI tlists")
- RHS
a tlist built with "M2SCI" functions, representing the Right Hand Side member of the instruction.
- eq
tlist of type "equal"
Description
This function create a tlist representing an instruction when using M2SCI.
All input parameters values are verified to be compatible with "M2SCI tlists".
Examples
Let's define the pseudo-code representing the simple statement
A = "off":
Let's define the pseudo-code representing the statement
A(2,:) = "off" :
// A LHS = Variable("A", Infer(list(Unknown,Unknown),Type(String,Unknown))); // A(2,:) LHS = Operation("ins", list(LHS,Cste(2),Colon), list()) // Insertion // A(2,:) = "off" Equal(list(LHS), Cste("off"))
Let's define the pseudo-code representing the expression
handles(:).axes_reverse(:,2) = "off", where
handles is a 1x3 row of graphical (axes) handles:
h = Variable("handles", Infer(list(1,3),Type(Handle,Unknown))); // Building the Left-Hand-Side part of the assignment (Equal): // handles(:) LHS = Operation("ins", list(h,Colon), list()); // Insertion // handles(:).axes_reverse : LHS = Operation("ins", list(LHS,Cste("axes_reverse")), list()) // Insertion // handles(:).axes_reverse(:,2) : LHS = Operation("ins", list(LHS,Colon,Cste(2)), list()); // Insertion // .. and finally the full statement: s.statement = Equal(list(LHS), Cste("off"))
---> s.statement = Equal(list(LHS), Cste("off"))
