Calcmatr

Calcmatr is a relatively simple application designed to help you perform calculations with matrices and equation systems. The elements, either fractions or integers, can be defined by the user or generated automatically.

The application is fully portable and does not rely on any third-party software, which means it can be saved on a portable storage device and launched on any PC that meets the OS requirements.

Whether you insert the elements yourself or have the application generate them automatically, you can create multiple matrices and use them in various operations.

They are all displayed in a left-hand panel, and you can select any of them to insert the contained values into the calculator. Each matrix can be made up of a maximum of four rows and five columns.

Moreover, it is possible to define a chain of operations involving multiple matrices.

Calcmatr can generate a specified number of matrices, and each of them is assigned a certain latter. When you select one of them, the elements are inserted into the calculator and can be edited or processed.

It should be noted that the results replace the original values, so you should ensure the matrix has been added to the collection before performing any operation.

It is possible to create an equation system from the current matrix or have the program generate a random one. You can define and solve systems of up to four equations and four unknowns.

Calcmatr is easy enough to use, and the bundled manual does a good job of explaining the program’s more advanced functions.

The interface is fairly outdated, however, and its layout may prove to be a bit confusing for first-time users.

Overall, Calcmatr is a handy, portable utility that allows you to perform a wide range of operations involving matrices. It supports equation systems and can generate sample data automatically.
