supposed that x and y are vectors of equal length > 1, what would happen when the following lines of code are executed? subplot(2,1,1); plot(x, y); subplot(2,1,2); pie3(x); in matlab

The given code tries to plot two different types of charts line plot and 3D pie plot using subplot command in Matlab. However, since pie3 function requires an argument with non-negative elements that sum up to a positive value (which is the proportion of each wedge), using x as an argument here will not make much sense (except probablty in some edge cases).

So, the program will throw an error for the second subplot.

Here is some sample code that can be used to visualize two different charts via subplots.

main.m
% Creating sample vectors
x = 1:5;
y = rand(1, 5);

% Subplotting two different charts
subplot(2,1,1);
plot(x, y);
title('Line plot')
xlabel('x-axis')
ylabel('y-axis')

subplot(2,1,2);
pie3([10 20 30 40], {},{'Apples','Bananas','Cherries','Dates'});
title('3D Pie plot')
271 chars
15 lines

This will create two subplots with a line plot in one and a 3D pie plot in another.
