Good day to all, i want to plot the matrix but here is a problem...

with(plots);

with(LinearAlgebra);

x(t) := `<|>`(`<,>`(.9582+1.9874*t-2.059*t^2+2.6184*t^3-3.7508*t^4, 1.11935+1.4898*t-.6319*t^2+1.037*t^3-1.4695*t^4))

matrixplot(x(t), t = 0 .. 4)

Error, (in plots/matrixplot) cannot convert first argument to a floating-point matrix

please help me...... how to solve this?
