Compatibility Check for Arrays and Matrices

Note
This topic does not apply to arrays/matrices used as messages.

The compatibility of two arrays or matrices is checked on the following occasions:

an array/matrix element is assigned to an array/matrix reference
an array/matrix element is passed as method argument
an array/matrix element is returned by a method
an array/matrix element is used as initialization value for an array/matrix reference

An array/matrix element can be assigned to an array/matrix reference if the following criteria are met:

both arrays/matrices have the same base type (cont, limitInt, wrapInt, sdisc, udisc, log, enumeration, record)
AND
both arrays/matrices have the same number of dimensions
AND
the element implementation type is identical (value range, formula, limitation)
AND
the respective dimensions are compatible in the following sense:
- an array/matrix with fixed max. size can be assigned to an array/matrix reference with identical fixed max. size
  OR
- both arrays/matrices are of variant size determined by identical system constants
  OR
- an array/matrix with fixed max. size can be assigned to an array/matrix reference with variant max. size (the equality of the sizes is checked during code generation or compilation)
  OR
- an array/matrix with variant max. size can be assigned to an array/matrix reference with fixed or variant max. size (the equality of the sizes is checked during code generation or compilation)
  OR
- an array/matrix with fixed, variant or variable max. size can be assigned to an array/matrix reference with variable max. size
AND – for arrays/matrices of enumeration or record types -
both array/matrices use identical enumerations or records

Note
Different from ASCET V6.2, an array/matrix with fixed max. size cannot be assigned to an array/matrix reference with larger fixed max. size. Code generation for existing models that use such assignments will fail. It is recommended that you convert the array/matrix references in these models to arrays/matrices with variable size, either manually or for the entire database.
