# How to create a matrix in sage that expands with a variable number of rows and columns and in each row the values are squared?

I need to make a code that takes takes two inputs: n and d and creates a matrix of the values of a list P.

'n' will be the number of columns and 'd' the number of rows.

In each row, I need the values of the following row to be raised to an incrementally rising power.

This is what I have so far:

# define inputs

n=5 d=5 f=x^2

# define a list of size n

P=[(i,f(i)) for i in range(n)]

# define a matrix

C=matrix([(P[i][0]) for i in range(n)]) show(C)

Please mark the

`python`

and`sage`

code as such, just mark it and pres`Control+K`

. (Or hit that button with the two rows`101`

and`010`

in the header of the question area.The above looks (slightly changed) like:

Please describe mathematically which is the matrix that should be defined.

Try ?matrix in the sage interpreter to see more examples.
