Do a couple of exercises to practice the syntax and you’ll be in a good position to use it where necessary.įor any questions, observations and queries regarding this article, use the comment form below. IF ELSE conditional statements are very common in any programming language. If (currentHour > 8) & (currentHour 10) & (currentHour 12) & (currentHour 12.3) & (currentHour <= 16) then Using ELSEIF statements design a script which displays in the Scilab console what activity is performed function on the current hour. In the image below you can see a logical diagram of the IF ELSEIF conditional statement for the sign() function: Scilab has it’s own built-in sign function called sign(). If (currentHour > 7) & (currentHour 0.\end\] The best way to practice this example is by using the Scilab script editor, SciNotes, in which we write the following Scilab instructions: currentHour = 14 If the current hour is NOT between 7:00 and 19:00 we say it’s not day (it is night). If the current hour is between 7:00 and 19:00 we say it is day. The general structure of an IF ELSE statement in Scilab is:Ī quite easy example is to define if it’s day or night function of the current hour. Data computed on grids coming from meshgrid() will require being transposed (please see the example thereafter). Hence, the matrix or hypermatrix X is made by replicating the vector x as all its columns. of 'template' coordinates sampled along each direction/dimension of the space that you want to mesh. work with grids generated with ndgrid(), not from meshgrid(). The first application of ndgrid is to build a grid of nodes meshing the 2D or 3D or N-D space according to 2, 3, or more sets x, y, etc. This field contains the handle of the parent figure. Most of Scilab 2D or 3D graphical functions like champ(), grayplot(), Sgrayplot(), plot3d(), contour(), etc. This entity defines the parameters allowing the change of coordinates and the axes drawing as well as the parameters default values for the children creation.
