Could you post the actual code and not a picture of it?

M=m+2;
m=83;
N=10
V=linspace(1,10,N);
E=6;
L=4;
A=5;
U=1/2.*M.*V.^2.
F=sqrt((U*2*E*A)/L)
X=U.*2./F
if (X>L)
X=0
elseif X<L
plot(V,X)
end
a=(gradient(V,X).*V)
FP=m.*a

If X is your data and L is the number.
X(X>L) = [] ; % this removes elements from X which are larger than L
