Console usage
Symja can be used as computer algebra system in a REPL
Make sure that a Java 11 runtime environment (JRE 11) is installed. At a terminal you can type java -version to see if it is installed.
Download the latest Symja release from
Unzip the download in a separate folder and run the bin\symja.bat file to use your Java installation path to run the Symja Console:
"%JAVA_HOME%\bin\java" -classpath "lib/*" org.matheclipse.io.eval.Console Alternatively, if you're using Maven you can run this Maven command:
mvn -f pom.xml exec:java@symja -pl matheclipse-io The available predefined function names in the console are described in the
