8.7.2. Matrix friendly functions

MindOpt Python SDK Matrix friendly functions

Methods

hstack()	Stack a tuple of matrices in sequence horizontally
vstack()	Stack a tuple of matrices in sequence vertically
concatenate()	Concatenate a tuple of matrices along an axis

hstack(tup)

Stack a tuple of matrices in sequence horizontally. It has the same the same behavior as numpy.hstack .

Parameters

tup –

A tuple of matrices to stack. Supported element types include:

• MVar

• MLinExpr

• MQuadExpr

• MConstr

• MQConstr

example:

x = model.addMVar((3, 3))
y = model.addMVar((3, 3))
hstack((x, y))

vstack(tup)

Stack a tuple of matrices in sequence vertically. It has the same the same behavior as numpy.vstack .

Parameters

tup –

A tuple of matrices to stack. Supported element types include:

• MVar

• MLinExpr

• MQuadExpr

• MConstr

• MQConstr

example:

x = model.addMVar((3, 3))
y = model.addMVar((3, 3))
vstack((x, y))

concatenate(tup, axis)

Concatenate a tuple of matrices along an axis. It has the same the same behavior as numpy.concatenate .

Parameters

• tup –

  A tuple of matrices to concatenate. Supported element types include:

  • MVar

  • MLinExpr

  • MQuadExpr

  • MConstr

  • MQConstr

• axis – The axis along which the matrices will be concatenated.

example:

x = model.addMVar((3, 3))
y = model.addMVar((3, 3))
concatenate((x, y), 1)
