The following functions of dense matrices can be imported from
cvxopt.base.
sqrt(
x)
The elementwise square root of x. The result is returned
as a real matrix if x is an integer or real matrix and
as a complex matrix if x is a complex matrix. Raises an
exception when x is an integer or real matrix with negative
elements.
sin(
x)
The sine function applied elementwise to x.
The result is returned as a real matrix if x is an integer
or real matrix and as a complex matrix otherwise.
cos(
x)
The cosine function applied elementwise to x.
The result is returned as a real matrix if x is an integer
or real matrix and as a complex matrix otherwise.
exp(
x)
The exponential function applied elementwise to x.
The result is returned as a real matrix if x is an integer
or real matrix and as a complex matrix otherwise.
log(
x)
The natural logarithm applied elementwise to x.
The result is returned as a real matrix if x is an integer
or real matrix and as a complex matrix otherwise.
Raises an exception when x is an integer or real matrix with
nonnegative elements, or a complex matrix with zero elements.
mul(
x, y)
The elementwise product of x and y.
The two matrices must have the same size and type.
div(
x, y)
The elementwise division of x by y.
The two matrices must have the same size and type.
