QUAD will call your function with a vector of inputs, not just a scalar. So if, say, your function were f(x) = 3*sin(x)*cos(2*x), you would need to bear in mind that x is a vector, so sin(x) is a vector and likewise cos(2*x) is a vector. You con't need to use ...
I am trying to find the jacobian for a transformation matrix. I am using symbolic variables (T, l, m, n). Each of these variables are function of 4 others variables (delta1 delta2 delta3 and delta4), as: symsu v w p q r phi theta psi x y z; ...

MATLAB also accepts logical indexing, which can be useful when working with conditional statements. For example, say you want to know the values of "A" that is larger than 7. Use the > operator to return a logical array whose elements are logical 1 when an e...
