Generate grid lines of constant damping ratio (zeta) and natural Set(gca,'Xtick',xticks,'Ytick',yticks) to control the number and MATLAB - Overview MATLAB (matrix laboratory) is a fourth-generation high-level programming language and interactive environment for numerical computation, visualization and programming.
Returns the real part of a complex number, see also imagįind the value of k and the poles at the selected pointįind the scale factor for a full-state feedback system Print the current plot (to a printer or postscript file)įind the number of linearly independent rows or columns of a Returns a vector or matrix of ones, see also zerosĬompute the K matrix to place the poles of A-BK, see also ackerĭraw a plot, see also figure, axis, subplot. Was written to replace the MATLAB standard command nyquist to get more accurate Nyquist plots. If A is a table or timetable, then size(A) returns a two-element row vector consisting of the number of rows and the number of table variables. Produces a minimal realization of a system (forces pole/zeroĭraw the Nyquist plot, see also lnyquist. For example, if A is a 3-by-4 matrix, then size(A) returns the vector 3 4.
