Matrix transformations

Hi!

I'm starting to work with Scilab, and I'm trying to figure out how to work
with matrices.

My goal is to find a way to convert any point from one system into another.

My (failed) approach so far was to estimate the necessary rotation,
translation and scale; but it didn't work quite well, because the second map
is slightly distorted (probably due perspective).

Being a bit more specific:

I have the following points:

A = [
[52.363965, 4.892435],
[52.384611, 4.898272],
 [52.379267, 4.881105],
 [52.369678, 4.911489],
]


They correspond to these points:

B = [
[0, 0],
 [2131, 1534],
[2131, 0],
[0, 1534],
]

Do you have any suggestions on how to calculate tje transform from A to B?

Thanks in advance,

Cap.
