x=-20:0.01:20; y=x.*x+2; plot(x,y( :,20))后面的(x,y( :,
x=-20:0.01:20; y=x.*x+2; plot(x,y( :,20))后面的(x,y( :,
x=0:0.01:100; y=2^x.; plot(x,y) 为什么出错?
mathematica,可以画出 Plot[n,{x,0,2Pi}] 但是 画不出 y=D[n,x] Plot[y,x]
x+y/2+x-y/3=6,4(x+y)-3(x-y)=-20
{(x+y)/2+(x-y)/3=6 4(x+y)-3(x-y)=-20
4(x+y)-3(x-y)=-20,2/x+y+3/x-y=6
matlab画图x = 0:0.01:10; y =sin(2*x)*cos(100*x)/(2*x); plot(x,
mathematica软件,已知y[x],Y=f1(x),X(x)=f2(x),如何plot Y[X]?
有这样一道题,计算:(x-y)[(x+y)(x+y)-xy]-(x-y)[(x-y)(x-y)+xy]的值,其中x=20
x=0:0.001:2; y=humps(x); plot(x,y); 如何求其最大值,需要matlab的程序?
Matlab的作图命令,x = 0:pi/100:2*pi; y = sin(x); plot(x,y)
matlab中如何画图!x=-pi:0.1:pi; y=cos(x)/cos(2*x);plot(x.y)
