One issue is that we are using 'm' but not passing any value to it.

In the Matrix component, the prop 'm' is used to determine the size of the grid. If 'm' is undefined, the component will create an empty grid or throw an error when trying to use it in array length or CSS grid template. To fix this, ensure that the parent component passes a numeric value for 'm', or provide a default prop value. For example:

interface MatrixProps {
  m?: number;
}

export default function Matrix({ m = 3 }: MatrixProps) {
  // ...
}

This way, if 'm' is omitted, it defaults to 3. Additionally, you can add PropTypes or TypeScript type checks to enforce that 'm' is a positive integer, preventing runtime errors and making the component more robust.
