Variables¶

A¶

• variable axis_params_v Inline variable form of axis_params for use in expressions.

C¶

• variable cindex Variable template form of cindex_t .

D¶

• variable dynamic_shape Sentinel rank value indicating a run-time-determined rank.

E¶

• variable expression_dims Inline variable holding the number of dimensions of an expression.
• variable expression_random_access Inline variable indicating whether an expression supports random access.

F¶

• variable fixed_shape Convenience variable template for instantiating a fixed_shape_t .

I¶

• variable infinite_size Sentinel value denoting a dimension of unbounded/unknown size.
• variable is_arg Inline variable that is true when T (after decay) is a numeric or boolean type and can therefore be passed by value as an argument.
• variable is_expr_element Inline variable that is true when T is a non-cv-qualified scalar vector element type.
• variable is_infinite Inline variable that is true when the shape of E is infinite.
• variable is_input_expression Inline variable that is true when E satisfies input_expression .
• variable is_input_output_expression Inline variable that is true when E satisfies input_output_expression .
• variable is_output_expression Inline variable that is true when E satisfies output_expression .

M¶

• variable max_index_t Maximum representable value of index_t .
• variable max_sindex_t Maximum representable value of signed_index_t .
• variable maximum_dims Upper bound on the number of dimensions supported by shape .
• variable maximum_expression_width Maximum vector width (in elements) supported by an expression handle for type T.

S¶

• variable seed_from_rdtsc Tag value used to seed the random number generator from the CPU cycle counter.
• variable symmetric_linspace

U¶

• variable undefined_size Sentinel value denoting a dimension whose size is not yet known.
