(lsh/libidx/idx-macros.lsh) |
A set of macros and functions to resize vectors, matrices and tensors.
7.7.0.0.0. (midx-m1resize m n0)
|
(lsh/libidx/idx-macros.lsh) |
a macro redims idx1 m in-place with

7.7.0.2.0. (cinline-idx1loop m type c j p1 [p2...])
|
(lsh/libidx/idx-macros.lsh) |
man, that's a tough one to explain. don't try this at home anyway. this
thing is like a loop for cinline. It executes the cinline instructions
in p1 ... for each element of matrix
m (must be an idx1). c ,
and j must be strings containing valid
C variable identifiers, and type is a
string that must contain a valid C type (like "float"). during the loop,
C variable c will point to the current
element of m , and C variable
j will contain the index of that element. So a macro that
fills the elements of a vector with its index plus a constant n can be
written:
(cinline-idx1loop mat "flt" "p" "i" (cinline "*p = i+%s;" n))
7.7.0.2.1. (cinline-idxloop2 m1 type1 m2 type2 c1 c2 j p1 [p2...])
|
(lsh/libidx/idx-macros.lsh) |
same as cinline-idx1loop, but loops simultaneously on two vectors
7.7.0.2.2. (cinline-idxloop3 m1 type1 m2 type2 m3 type3 c1 c2 c3 j p1 [p2...])
|
(lsh/libidx/idx-macros.lsh) |
same as cinline-idx1loop, but loops simultaneously on three vectors
7.7.0.2.3. (cinline-idx2loop m type c i j [l1...])
|
(lsh/libidx/idx-macros.lsh) |
same as cinline-idx1loop but loops over all elements of an idx2.
i and j are strings
containing the C name of the row and column indices.
7.7.0.2.4. (cinline-idx2loop2 m1 type1 m2 type2 c1 c2 i j [l...])
|
(lsh/libidx/idx-macros.lsh) |
same as cinline-idx1loop2 but loops over all elements of an idx2.
i and j are strings
containing the C name of the row and column indices.
7.7.0.2.5. (cinline-idx2loop3 m1 type1 m2 type2 m3 type3 c1 c2 c3 i j [l...])
|
(lsh/libidx/idx-macros.lsh) |
same as cinline-idx1loop3 but loops over all elements of an idx2.
i and j are strings
containing the C name of the row and column indices.
