## Example
https://godbolt.org/z/Te74xc414
```hlsl
//------------------------------------------------------------------------------
// 5) Zero-based (._m<row><col>) and one-based (._<row><col>) point accessors
// Works on matrices and returns a scalar element.
//------------------------------------------------------------------------------
float2x2 A_scalar = float2x2(1, 2,
3, 4);
export float fn() {
float z00 = A_scalar._m00; // zero-based row=0 col=0
float z10 = A_scalar._m10; // row=1 col=0
float o11 = A_scalar._11; // one-based row=1 col=1
float o21 = A_scalar._21; // row=2 col=1 (if size allows)
return z00 * z10 * o11 * o21;
}
```
## TODO
- [ ] Add functions to parse and validate matrix point accessors
- [ ] Modify SemaExprMember.cpp to handle matrix point accessors
- [ ] Use `CheckExtVectorComponent` as an example
- [ ] Test the implementation
