I missed this lecture and am trying to figure it out so it doesn't bite me going forward.
My professor supplied us with this script which is supposed to display the M(x) piecewise, "momentfunctionarray.mlx" which reads as follows:
function y = momentfunctionarray(x)
len = length(x);
for i = 1:1:len
if x(i) >= 0 && x(i) < 3
y(i) = 265*x(i)-5.56*x(i)^3;
elseif x(i) >= 3 && x(i) < 6
y(i) = -50*x(i)^2 + 415*x(i) - 150;
elseif x(i) >= 6 && x(i) < 10
y(i) = -185*x(i) + 1650;
elseif x(i) >= 10 && x(i) <= 12
y(i) = 100*x(i) - 1200;
My problem is I don't know how to build the function that defines "x" for step 1 so that the piecewise can be useful.
