Question

Please help me on how to code this in matlab

Cales te
Example:
xrange -5:0.5:5; %the domain of x is from -5 up to 5 with 0.5 interval.
yrange -10:1:10; %the values of y is from -10 up to 10 with 1 interval.
[x,y] = meshgrid (xrange, yrange);
%plot the DE
y' = x^2+y^2;
S = x.^2+y^2;
quiver (x, y, ones (size(s)),s)
Exercises:
Sketch the direction fields of the following differential equations
1. y' = 0.25.xy²
2. y' = sin(x-y)
Notes:
For the ranges:
For Item No.1
Use xr1 = (-5,5) with 0.5 interval yr1 = (-10,10) with 0.5 interval
Use $1 for the f(x,y), x1 and y1 as the points in the rectangular coordinate system,
For Item No.2
Use xr2 = (-10,10) with 1 interval yr2 = (-6,6) with 0.2 interval
Use s2 for the f(x,y), x2 and y2 as the points in the rectangular coordinate system,
