Tutorial 15 – Some Miscellaneous Commands
Some commands related to operations on disks are important and they are
listed below. They are required when you want to change the directory in
which your function files are stored or from where they are to be read.
pwd Prints the name of the current working directory
getcwd() Same as pwd.
chdir('dir') Changes the working directory to a different disk
location named dir.
In version 5.1.1, changing directory has become easy and visual. In the
main menu, go to File Change current directory... and visually browse to the
folder which you want to make the current directory and click OK. The error prone
task of typing lengthy folder paths is no longer necessary.
It is possible to save all the variables in the Scilab Workspace to a disk file
so that you can quickly reload all the variables and functions from a previous
session and continue from where you left off. The commands used for this
purpose are:
save('pf.bin')
Saves entire contents of the Scilab workspace
(variables and functions) in the file pf.bin in the
current working directory.
load('pf.bin') Restores contents of the Scilab workspace from the file
pf.bin in the current working directory.
save('pf.bin', xy) Saves only the variable xy of the Scilab workspace in
the file pf.bin in the current working directory.
It is possible to determine the size of variables in the Scilab workspace
with the following command:
size(x) Returns a 1x2 matrix containing the number of rows
and columns in the matrix x.
length(x) Returns the number of elements in matrix x (number
of rows multiplied by number of columns).
clc Clear the screen. Alternately, you can press the F2
function key
Scilab maintains a history of the commands typed at the command
prompt. You can scroll up and down the command history with the up
arrow () and down arrow () keys on the keyboard. You can move to the left
and right along one of the previous commands from the command history with
the left arrow (), right arrow (), Home and End keys on the keyboard. You
can delete any of the characters with the Delete or Backspace keys. Insert new
characters. You can press the Enter key to complete the command.
