MAE 284 EXAM 1 NUMERICAL METHODS
Bracketing methods always require two initial estimates - Answer -True
The incremental search method is typically very fast, even when employing a high
degree of precision. - Answer -False
A bracket with opposite-signed function values always contains exactly one root. -
Answer -False
Inspect the line of code below and match each item with its definition from the drop
down boxes: - Answer -x1
The root of the function
Fzero
The name of the in-built MATLAB function
F
The function to be evaluated
100
The initial guess for the root location
The Newton-Raphson method may not converge. - Answer -True
MATLAB's built-in fzero function requires three arguments: a function handle, a value
for the left bracket and a value for the right bracket. - Answer -False
MATLAB's fminbnd function creates two matrices that can be used to create a 3D mesh
plot of a function of two independent variables. - Answer -False
In general, a numerical solution is an exact solution. - Answer -False
___ suppresses outputs to the command window and separates rows in an array. -
