## How do I plot a circle in Scilab?

The analytic equation of circles is: (x – xc)² + (y – yc)² = r² where (xc, yc) means the center of the circle and r is it radius.

We know cos²(a) + sin²(a) = 1, for any angle a, thus multiplying both sides of equation by r² we obtain (r cos(a))² + (r sin(a))² = r²..

## How do I use Scilab?

The ﬁrst way is to use Scilab interactively, by typing commands in the console, analyzing the results and continuing this process until the ﬁnal result is computed. This document is designed so that the Scilab examples which are printed here can be copied into the console.

## How do you plot on Scilab?

## How do you use the subplot function in Matlab?

subplot( m , n , p ) divides the current figure into an m -by- n grid and creates axes in the position specified by p . MATLAB® numbers subplot positions by row. The first subplot is the first column of the first row, the second subplot is the second column of the first row, and so on.

## What is GCA in Scilab?

gca – Return handle of current axes.

## What is the difference between plot and subplot in Matlab?

Normally whenever we draw a graph we join each of the neighbouring points with one another. But using stem function you plot the discrete functions,i.e.,without joining the coordinates. If you want to join the points use the plot() function. You can try using both plot and stem functions at same place using subplot.

## How do you make a 3d plot in Scilab?

## What is the command to clear the screen in Scilab?
