mlfColon (C Math Library Reference)

Create vectors and use in array subscripting

C Prototype

mxArray *mlfColon(mxArray *start, mxArray *step, mxArray *end);

Arguments
mxArray *start
Initial value.

mxArray *step
Increment value, or final value if only start and end values are specified.

mxArray *end
Final value, NULL if only start and end values are passed.

Description

This function lets you specify a vector index.

Example

This example specifies the vector [ 1 2 3 4 5 6 7 8 9 10 ].

mxArray *vector_index = NULL;

mlfAssign(&vector_index,
          mlfColon(mlfScalar(1), mlfScalar(10), NULL));

This example is equivalent to a call to mlfCreateColonIndex().

mxArray *colon = NULL;

mlfAssign(&colon, mlfColon(NULL,NULL,NULL));
