Scilab2023简单的尝试
因为种种原因,不能使用Matlab,就接触到了Scilab,有一阵子没有使用了,突然发现被达索收购了。
随便抄一段代码:
clear, clc, clf; wn = 2; instants = 0:0.05:20; kexi = [0.1, 0.5, 1.0, 2.0]; for i = 1:length(kexi) s = poly(0, 's'); h = wn^2 / (s^2 + 2*kexi(i)*wn*s+wn^2); s1 = syslin('c', h); y = csim('step', instants, s1); y1(i, 1:length(y)) = y; z = csim('imp', instants, s1); z1(i, 1:length(z)) = z; end clf(0); scf(i); show_window(); xsetech([0.0, 0.0, 1.01, 0.51]); plot("onn", instants', y1') xtitle("阶跃响应","t","y");xgrid() legend(["ξ=0.1";"ξ=0.5";"ξ=1";"ξ=2"]) xsetech([0.0, 0.5, 1.0, 0.5]); plot("onn", instants', z1') xtitle("脉冲响应","t","y");xgrid() legend(["ξ=0.1";"ξ=0.5";"ξ=1";"ξ=2"])
运行后的效果如下:
尝试一下,调整坐标显示的字体大小,新版是可以调整了的。
