LIBRARY
Math.Tests.LinearDependency
Computes a linear combination of constant and time-varying inputs.
Connects constant sources with values 2 and 3 to a LinearDependency block with y0=1, k1=2, k2=3, and verifies that y = 1 + 2_2 + 3_3 = 14. A second LinearDependency block with the same coefficients is driven by two sine waves that sweep negative and positive values.
