Here in this question we have to find the least square solution.
00:06
So, least square solution of the linear equation, that is a of x, is equal to b, is the solution of x that is consisting an equation that is ax -dash, which is equal to b of call of a.
00:20
So the coefficient of matrix a of the linear system a will be, like a table, it was like this.
00:35
1 -1 minus 1, 250, minus 1, minus 3 1 and 261.
00:48
So, determinant of call of a, we need to reduce it, a in its rr, e, f, which is like, so this equation was somewhat like this, 1, 1 ,0, 0 ,0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1...
