This homework is taken from the course [[http://floatium.stanford.edu/ee263|EE263]] at Stanford (see section Homework).
File which include all homeworks for this subject you can find in [[http://floatium.stanford.edu/ee263/hw/ee263hw2.pdf|this file]].

You will deal with the task **6.15**. Data which are needed to this task you can download here:

  * [[http://floatium.stanford.edu/ee263/hw/qplace_data.m|qplace_data.m]]
  * [[http://floatium.stanford.edu/ee263/hw/view_layout.m|view_layout.m]]

Proceeds the task exactly as entered, thus solve points a), b). Message (with answer to theoretical questions) provide in PDF and Matlab's code to uploaded system.

The task is on the least squares method, therefore, the aim is to formulate it in the form of $\min_{\_x}\|\_P\_u-\_q\|_2^2$ and then count solutions using Matlab command backslash. Solutions can be written in few Matlab's line, if you can work with block matrices. Your code should not contain any loop (for, while).
