Suppress command output. - t_angenbrandt - 05-13-2021 08:04 AM
Good morning.
Is it possible to suppress command outputs (e.g. like in matlab, where one uses a semicolon at the end of a command)?
The issue is that while working with giant matrices or CAS results from integrals that normally would fill multiple lines on a sheet of paper, the calculator is busy rendering the results instead of doing useful calculation; I am not interested in the outputs of the commands (e.g. I simply store the result of a program function in some variable to work with it).
If there is no way, maybe I can do something like write a function that takes a command, executes it and stores the result in a variable without producing a return value no?
Can I pass a function with all its arguments as an argument like that: suppress(var, func(a,b,c,d,e,f)) or would that not be possible?
Kind regards

zero(x) := 0
Cas> zero(m:=makemat((j,k)->j+k,3,2)) → 0
Cas> zero(m := transpose(m)) → 0
Cas> m → [[2,3,4],[3,4,5]]

A godsend. Why did I not see this.

XCas suppressing output shortcut ":;" also work in HP Prime emulator.
CAS> m := makemat((j,k)->j+k,3,2) :; → "Done"
