Portamatrices

Portamatrices is a term used to describe a portable holder or containment system designed to organize and secure multiple matrices in educational, laboratory, or computational contexts. The most common use is as a teaching aid in linear algebra classrooms, where instructors present several matrices on a single board or stand to compare properties, perform row and column operations, or illustrate matrix multiplication.

Physical portamatrices consist of a rigid frame with a grid or array of slots sized to accommodate matrix cards or tiles. Each slot is labeled with dimensions and may include magnetic strips or clamps to hold entries in place. Some models feature interchangeable sleeves for different matrix sizes, and color-coded borders to indicate orientation or operation type.

In computational contexts, the phrase portamatrices can refer to software components or data structures that group and transfer matrices between modules. A portamatrix container provides a uniform interface to access, modify, or serialize matrices, supporting operations across formats or languages.

Variants and history: There is no single standardized design; portamatrices have appeared in various forms, from simple teaching kits to modular lab frames. The concept is linked to hands-on education and to software engineering practices that emphasize modular data handling in linear algebra processes.
