Category(ies):
Lists and Matrices, Math
Description:
Pushes onto the estack a matrix (the input of which is indexed by
mat_idx
)
which is the result of multiplying an expression (indexed by
mult_idx
) by all
of the elements in a row (indexed by
mult_row_idx
) and adding those
elements to another row (indexed by
add_row_idx
).
row(
add_row_idx
) = row(
mult_row_idx
) *
mult_idx
+ row(
add_row_idx
)
Inputs:
mult_idx
— Indexes the multiplier expression.
mat_idx
— Indexes the input matrix.
mult_row_idx
— Indexes the row to multiply by
multi_idx
.
add_row_idx
— Indexes the row to add the values from the row
indexed by
mult_row_idx
.
