SUMMARY

The discussion centers on finding the best-fit line in the form of y = mx + c using matrix-vector formulation in MATLAB. The user initially sought assistance but later resolved the issue independently. The key takeaway is the application of matrix operations in MATLAB to derive the coefficients m (slope) and c (intercept) from a set of x-y values.

PREREQUISITES
  • Basic understanding of linear regression concepts
  • Familiarity with MATLAB programming environment
  • Knowledge of matrix operations and vector manipulation

I am learning how to use MATLAB and have this problem:
Find the best-fit line of the y= mx + c form. Use matrix-vector formulation. And i am given a table of x-y values.

I have no idea how to proceed. Any help is welcome.

Nevermind, i figured it out.
