比如求该分段函数与f=0.4的交点解析解并绘图: % 定义分段函数 syms x % 变量 分段点 每段上的函数 端点处的函数 f=piecewiseSym(x,[-1,1],[-x-1,-x^2+1,(x-1)^3],[-x-1,(x-1)^3]); % 求解 S=solve(f==.4,x) % 绘图 xx=linspace(-2,2,500); f=matlabFunction(f); yy=f(xx...
Solve a Matrix equation Hi, I was struggling in this equation for serveal days. A' * B * A =P Solve A. A is an unknown 4X1 complex matrix and A' is the transpose conjugate of A. B is a known 4X4 complex matrix. P is 1X1. Do anybody know how to solve it on the matlab? H...
eval: 将sym符号转换为数值 syms: 定义符号变量 dsolve: 求解常微分方程, 求出符合条件的一个函数 solve: 求解方程组, 可以偷懒了:-) matlab中的''和""是不一样的, 建议以后使用"", 因为s = ["hello", "world"]和['hello', 'world']返回的结果是不一样 linprog -> 使用单纯形法计算出最小的最优...
Matlab中solve函数主要是用来求解线性方程组的解析解或者精确解。对于得出的结果是符号变量，可以通过vpa()得出任意位数的数值解。solve函数的语法定义主要有以下四种：g = solve(eq1, eq2, ?, eqn, var1, var2, ?, varn)solve(eq1, eq2, ?, eqn)solve(eq, var)solve(eq)...
它的输入、功能和输出都和solve相仿。方程组的输入同样为行向量,变量组的输入也一样。 当输入一个可以定解的多项式方程(组)时,vpasolve将会直接给出方程的数值解;若多项式方程数量不足以确定所有的解,那么vpasolve将会给出以剩余变量表示的所求变量的函数,只是表达式的一部分(系数等)可能会以数值的形式呈现。注意,...
Instead of using the block flow method shown above, I would like to solve this problem using the matrix of ODE equations shown below. How would I utilize this matrix below to simulantenously solve my two differential equations. Utilimately, I will have six equations. If I can solve just ...
