These notes have been triggered by physicist's considerations on (1)'Pre-quantized wave equations' for matter fields, (2) Conservation laws, (3) Gauge Field extensions. All starting from variational principles. These notes do not contain functional analysis or differential geometry. Only bare elementary considerations on matrix-valued functions. As a motivation there is a lengthy preface/summary.
