The data type (class) must be a built-in MATLAB ® numeric type. For other classes, the static randn method is not invoked. For example, randn(sz,'myclass') does not invoke myclass.randn(sz). Size arguments must have a fixed size. See Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder).. If extrinsic calls are enabled and randn is not called from inside a ...
