Constructor Detail

DoubleIR

public DoubleIR(DoubleMatrix1D template)
Constructor for IR. Uses the given vector as template for creating scratch vectors. Typically, the solution or the right hand side vector can be passed, and the template is not modified

Parameters:
template - Vector to use as template for the work vectors needed in the solution process
