Solve a Matrix for unknows in Python / Numpy / Scipy -

i need solve system of matrices unkowns u4,f1,f2,f3,f5 , f6 particular fea problem. have generated matrix containing numbers input , need solve these knowns.

• the code should act follows:

  0 + 0 + 0 + 150*1000*u4 + 0 + 0 = −1732

therefore, u4=-0.01154

• so other unknowns can found out follows:

  0 + 0 + 0 + (43:4)(−0:0115) 1000 + 0 + 0 = f1

therefore f1=-500 , on....

i beginner , familiar basics of numpy , python oop. please me set code this.

in [0]: import numpy np      in [1]: = np.random.rand(6,6)  in [2]: a4 = a[3,:]  in [3]: u4 = -1732/a4[3]  in [4]: f = a4*u4  in [5]: f out[5]:  array([ -246.6101995 ,  -589.6732277 ,  -574.67690895, -1732.        ,        -2592.99948033, -2383.52077134]) 

replace a or atleast fourth column a4 data...
