Remembering Variables In for Loop
显示 更早的评论
I wrote the following code
no_of_values=input('How many Values of the independant valriable (x) are there');
for i=0:1:no_of_values-1
x_i=input(['Enter the value of x_ ',num2str(i)]);
y_i=input(['Enter the value of y_ ',num2str(i)]);
end
I want to save the value of x_i and y_i after every iteration, like x_0 and x_1 etc. But when the loop ends Matlab only remembers x_i and y_i as
variables for the last values.
The error can be seen in the screenshot attached

for i=1:no_of_values
x(i)=input(['Enter the value of x_ ',num2str(i)]);
y(i)=input(['Enter the value of y_ ',num2str(i)]);
end
Matlab starts counting at 1 rather than 0.
Store the values in x(i) and y(i).

Don’t forget to preallocate and use sprintf() instead.
As madhan ravi wrote, preallocation would be a good idea (more efficient, avoid bugs):
