Which MATLAB function computes the Singular Value Decomposition of a matrix?
Answer: svd
svd decomposes a matrix A into U, S, and V such that A = U*S*V', where S contains the singular values.
What solver should you use for stiff ordinary differential equations in MATLAB?
Answer: ode15s
ode15s is designed for stiff problems, using a variable-order method based on numerical differentiation formulas.
What does `fmincon` do in MATLAB's Optimization Toolbox?
Answer: Minimizes a nonlinear function subject to constraints
fmincon finds the minimum of a nonlinear multivariable function subject to linear and nonlinear constraints.
Which MATLAB function performs the Fast Fourier Transform?
Answer: fft
The fft function computes the discrete Fourier transform of an input vector using the Fast Fourier Transform algorithm.
What does `interp1(x, y, xq)` do in MATLAB?
Answer: Interpolates values at query points xq using data (x, y)
interp1 performs 1-D data interpolation, estimating values at query points xq based on known data pairs (x, y).
What is the purpose of `chol(A)` in MATLAB?
Answer: Computes the Cholesky factorization of a symmetric positive definite matrix
chol(A) returns the upper triangular Cholesky factor R such that R'*R = A, valid only for symmetric positive definite matrices.
