matlab双曲函数
matlab：
x= -10:0.1:10;
sinhx = (exp(x)-exp(-x))/2;
coshx = (exp(x)+exp(-x))/2;
tanhx = (exp(x)-exp(-x))./(exp(x)+exp(-x));
figure(1),plot(x,sinhx,'r-'),legend('双曲正弦函数sinh(x)');
grid on;
figure(2),plot(x,coshx,'g-'),legend('双曲余弦函数cosh(x)');
grid on;
figure(3),plot(x,tanhx,'b-'),legend('双曲正切函数tanh(x)');
grid on;结果如图：
