一。用matlab 中的solve函数 >>syms x y; %定义两个符号变量；>>[x ,y]=solve('y=2*x+3','y=3*x-7');%定义一个 2x1 的数组，存放x，y >>x >>x=10.0000 >>y >>y=23.0000 二。用matlab 中的反向斜线运算符（backward slash）分析：方程组可化为 2*x-y=-3；3*x-y...
Example 2: x² + 2x + 1 = 0 a = 1, b = 2 and c = 1 Δ = b² - 4ac Δ = 2² - 4.1.1 = 4 - 4.1 Δ = 4 - 4 = 0 x = -b ±√Δ2a x = -2 ±√02.1 x = -2 ±√02 Δ = 0, meaning that x₁ = x₂ = x. x = -22 = -1...
