## Solving system of linear equations with ...

Maple 13

Dears,  I have a system of linear equation A*X=B   where A matrix 607x400  & X vector  400x1 and B vector 400x1

where A not square matrix. To sove,  I do

(A^T)*A*X=(A^T)*B,

Let   D= (A^T)*A        D  square matrix

then

D*X=(A^T)*B,

the solution is

X= (D^-1)*(A^T)*B.

could any one help me to do this by maple and cut the resluts in...

## Maple 11 does not save...

## How can i plot a parametric equations...

Maple 11

Dears, How can i plot a parametric equations for an ellipse

x[i]=a*sin(t[i]),     y[i]=b*cos(t[i])      t[i] takes a numerical vaulues from - Pi to Pi.

i.e

i want to plot the values ,

(x[1], y[1]),

(x[2], y[2]),

.

.

(x[i], y[i])      where     i=1..100,
