关于用matlab求解函数
Y1=(-1.24E-10)*X1+(1.96E-10)*X2+(-2.59E-14)*X3+(3.46E-10)
Y2=(4.67E+5)*X1+(-6.82E+5)*X2+(-1.62E+4)*X3+(-6.92E+5)
Y3=(5.37E+4)*X1+(-8.37E+4)*X2+(-3.22E+3)*X3+(-4.28E+3)
SPSS求出一个Y(X)方程组,
类似:
Y1=a1*X1+b1*X2+c1*X3+d1(常数)
Y2=a2*X1+b2*X2+c2*X3+d2(常数)
Y3=a3*X1+b3*X2+c3*X3+d3(常数)
求解一个X(Y)的方程组,
类似:
X1=e1*Y1+f1*Y2+g1*Y3+h1(常数)
X2=e2*Y1+f2*Y2+g2*Y3+h2
X3=e3*Y1+f3*Y2+g3*Y3=h3
