I want to make a program to ask the user to input a number (lets say N) and then based on N, the user enters numbers, coordinates, or a list N times

 

Input example:

 

4

0,0

0,2

2,2

2,0

 

"How many rows"?->N

For 1->I to N

"X"?->Matrix A[I,1]

"Y"?->Matrix A[I,2]

Next

Mat [A]    //Not necessary, just a display test

 

Thanks!

Something like this?

 

I think you need to define the length of the matrix before hand, but I forgot how to do that at the moment.

Something like N->Dim Mat A

 

I think.

Your code provided what I was asking for and gave me some good insight on how to program matrices.

 

I'm not quite sure what the second for loop did as the last value I entered was displayed as a single value, however the inputs were saved into the matrix correctly

 

As for the dimensions of the matrix, I can input the size of them before hand, but I will play around with the calculator to see if I can program the size

I will update my current code

 

Thank you Sheepolution

The second loop was to show the results. But I see now that you edited your post and cut out that request.

 

Glad to help, and good luck.

Hello

 

If you want to define 3 x 3 Matrix A, 

 

[[0,0,0][0,0,0][0,0,0]] -> Mat A

 

 

Does it help?

@Krtyski, that's not quite what I was looking for, but I did figure out how to define the matrix rows based on the input N

"How many rows"?->N

{N,2}->Dim Mat A

for loop...

 

@flyingfisch, I don't see the "marked solved" button

[flyingfisch]

Should be under any posts in threads you started that are not your own...

@flyingfisch, I don't see the "marked solved" button

 

There was a misconfiguration on this particular forum, you should see the 'mark Solved' button now
