Defining parameters as vector

Hello everyone,
I am trying to define a parameter as a vector, but using {1, 2, 3} gives the error "Vector parameter definitions are not allowed". I tried different syntaxes but it seems that the probleme comes from the place where I try to define the vector.
I intend to use this vector as an argument for an external C function as it seems that Comsol can pass such argument. The external function is used to define boundary conditions.
Does anyone have any idea on either how to define parameter as vector or how to use vector as input for an external function ?
Thank you for your help.

Hi,
parameters in Comsol are scalars, which can take complex values. You can define vector components as parameters and pass those to the external function.

Hello Edgar, thank you for your response. Using complex values will only work for 2D vectors ? Also I may not have used the right word, I am trying to define an array for programming purpose which can store numerous information in a single parameter/variable, more than a vector in the mathematical way. Sorry for the mistake.

Well, the procedure will be the same. You need to split the structure into its scalar components and pass those to the external function.
