fzero with function in matrix
显示 更早的评论
I have to solve a matrix of function and then search the zero
I write a simpler code.
syms x
a=[sin(x),1;1,1];
b=[1/cos(x);1];
c=a*b;
y=c(1,1)-1;
fzero(y,[-1,1])
any suggest please?
I even tried to define the function in other way but then I wasn't able to solve the matrix product
f1=@(x)sin(x);
f2=@(x)(1/cos(x));
a=[f1,1;1,1];
b=[f2;1];

Insert the line
y=matlabFunction(y);
after you defined
y=c(1,1)-1;

syms x
a=[sin(x),1;1,1];
b=[1/cos(x);1];
c=a*b;
x=fzero( matlabFunction(c(1)-1) , pi/4 )
