The paper deals with six approaches how to determine a derivative of the matrix exponential function in the Matlab language environment. Namely, a Taylor series expansion, an augmented matrix utilization, an eigenvalues decomposition, a Laplace transform approach, a convolution integral evaluation and a...

Digital differentiation is defined as dx[n]/dn and can be calculated directly from the slope of x[n] by taking differences: (8.15)dx[n]dn=Δx[n]Ts=x[n+1]−x[n]Ts This equation can be implemented by MATLAB’s diff routine. This routine uses no padding, so the output is one ...
