Create an AST node for dimensions (dims) of a symbol

Constructs an dims object, which represents the declared dimensions of a variable, parameter, or equation in a structured symbolic model. Each dimension is typically represented as a set reference (set) or as a symbolic identifier (symbol). This is similar to index, but specifically for dimensions.

Usage

ast_dims(...)

Arguments

...

One or more dimension expressions, typically created using ast_set() or ast_symbol(). Expected AST objects or character strings, comma-separated. If character strings are provided, they will be converted to symbol objects.

Value

A list of class dims and ast, representing the dimension nodes.

Examples

ast_dims(list(ast_set("tech"), ast_set("region")))
#> <AST dims> 
#> [tech,region]
ast_dims(ast_symbol("t"))
#> <AST dims> 
#> [t]
