auto stan::math::as_column_vector_or_scalar ( T &&  a )

inline

as_column_vector_or_scalar of a kernel generator expression.

Converts input argument to a var_value<> with column vector or a scalar.

Converts std::vector to a column vector.

Template Parameters

T	type of argument

Parameters

a	input argument (must be a row or a column vector)

Returns

as_column_vector_or_scalar of given expression

Template Parameters

T	std::vector type.

Parameters

a	Specified vector.

Returns

input converted to a column vector.

For column vector inputs this is an identity function.

Template Parameters

T	Type of var_value.
