how can i fix this error?

clc

clear

x (1)= 0;

y (1)= 3;

h = 0.05;

for i = 1:10

y (i+1)= y(i)+(6*x^2-3*x^2*y);

x (i+1)= x(i)+h;

end

plot(x,y,'-')

xlabel('x')

ylabel('y')

Error using ^ (line 52)

Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a scalar. To perform elementwise matrix powers, use '.^'.

Error in odev1 (line 7)

y (i+1)= y(i)+(6*x^2-3*x^2*y);

You need to change x to x(i) and y to y(i) like this code.

clc
clear
x (1)= 0;
y (1)= 3;
h = 0.05;
for i = 1:10
    y (i+1)= y(i)+(6*x(i)^2-3*x(i)^2*y(i));
    x (i+1)= x(i)+h;
end
plot(x,y,'-')
xlabel('x')
ylabel('y')
