MATLAB: Not able to get plot

plot


x = linspace(0, 0.3,0.01);
y = ((384*0.5*((0.15).^(3/2)))./ (x.^(3/2))).^(1/2); %cr
figure
plot(x, y)

Hello,

You used the linespace function with wrong parameter. Here is instruction of linespace function:

linspace(X1, X2, N) generates N points between X1 and X2.

To get properly result, you change 0.01 by a proper number of intervals from 0 to 0.3.

m and p should have the same number of element. To correct this
m=0:2.5:12.5
p=0:0.2:1 
plot(m,p)

You can check the size of each vector

size(m)
size(p)

m=0:2.5:12.5 
p=0:0.2:1
x=p./m   % it's a multiplication element by element, the operator is ./ instead of /
plot(x,p)
