how to store array
显示 更早的评论
I have
for x=1:5
A=[5*x 0;2*x^2 1]
B=[0;2.55]
Y=A\B
end
How can I store 5 different matrices of 2X1 in excel

Try something like this —
xv=1:5;
for k = 1:numel(xv)
x = xv(k);
A=[5*x 0;2*x^2 1];
B=[0;2.55];
Y(:,x)=A\B;
end
Y
writematrix(Y,'YourFileName.xlsx')
Experiment to get the result you want.

After I created ‘xv’ I forgot to update the subscript in ‘Y’ (corrected here). My apologies.
xv=0:0.1:3;
for k = 1:numel(xv)
x = xv(k);
A=[5*x 0;2*x^2 1];
B=[0;2.55];
Y(:,k)=A\B;
end
Y
figure
plot(xv, Y, '.-')
grid
Beyond that, it works, however with any element of ‘xv’ being 0, there is going to be a NaN result, because the‘Y’ calculation results in a 0/0 operation, that result (or in a few similar situations) will be NaN.
