y1 = -10^(0.5.*x) + sin(x) * abs(x.^3 - 4.*x - 1);
Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the
power is a scalar. To perform elementwise matrix powers, use '.^'.
^ This is the error I am getting and I'm trying to fix it but I'm stuck.

Ran in:
You needed elementwise operations in several places that you did not use it:
x = 1:5;
y1 = -10.^(0.5.*x) + sin(x) .* abs(x.^3 - 4.*x - 1);
plot(x,y1)
