Solutions to phc: command not found

How To Fix phc: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu phc is provided by phcpack package.

phcpack is:

PHCpack is a software package to solve polynomial systems by homotopy continuation methods.

A polynomial system is given as a sequence of polynomials in several variables. Homotopy continuation methods operate in two stages. In the first stage, a family of polynomial systems (the so-called homotopy) is constructed. This homotopy contains a polynomial system with known solutions. In the second stage, numerical continuation methods are applied to track the solution paths defined by the homotopy, starting at the known solutions and leading to the solutions of the given polynomial system.

This package contains the command line interface to PHCpack.

To fix this problem, we can install more using the command below.

sudo apt-get -y install phcpack

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install phcpack.

sudo apt -y install phcpack

Or if you have aptitude installed you can use the following command.

sudo aptitude install phcpack
