Make an n × n random matrix a) calculates its inverse b) Multiply the two back together c) calculates the residual (difference from the desired n × n identity matrix eye(n))

 

Make an n × n random matrix
a) calculates its inverse 
b) Multiply the two back together
c) calculates the residual (difference from the desired n × n identity matrix eye(n))


Solution:

j=rand(2) k=inv(j)mul=k*j mul=k*j ide=mul-eye(2)
