Using the C Math Library

Assigning to All Elements 

You can use the colon index to replace all elements in a matrix with alternate values. The colon index, however, is infrequently used in this context because you can accomplish approximately the same result by using assignment without any indexing. For example, although you can write

mlfIndexAssign(&A, "(?)", mlfCreateColonIndex(),
               mlfRand(mlfScalar(3),NULL));

writing

mlfAssign(&A, mlfRand(mlfScalar(3), NULL));

is simpler.

The first statement reuses the storage already allocated for A. The first statement will be slightly slower, because the elements from the source must be copied into the destination.

Note    mlfRand(mlfScalar(3), NULL) is equivalent to mlfRand(mlfScalar(3), mlfScalar(3), NULL).
