绘制最优决策变量和相应的残差

如何解决绘制最优决策变量和相应的残差

我有这个 matlab cvx 设置用于我的问题来估计最小二乘解

saveEditProfile_studentbtn.setonClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
                String studentUser = firebaseAuth.getCurrentUser().getUid();

                final DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference("Users").child(studentUser);
                Toast.makeText(StudentProfileEditact.this,studentUser,Toast.LENGTH_SHORT).show();
                databaseReference.addValueEventListener(new ValueEventListener() {
                    @Override
                    public void onDataChange(@NonNull DataSnapshot snapshot) {
                        String replaceName = studentChangeFullName.getText().toString().trim();
                        String replacePhoneNumber = studentChangePhoneNum.getText().toString().trim();
                        Map<String,Object> updates = new HashMap<>();
                        updates.put("fullName",replaceName);
                        updates.put("phoneNumber",replacePhoneNumber);

                        databaseReference.updateChildren(updates);
                        Toast.makeText(StudentProfileEditact.this,"Changes has been made",Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onCancelled(@NonNull DatabaseError error) {

                    }
                });

            }
        });

由于 Cvx 在运行后显示最优值，我不知道如何生成最优决策值和残差图
