Article Title: Angularly resolved, finely sampled elastic scattering measurements of single cells: requirements for robust organelle size extractions
Article Snippet: The MATLAB downhill simplex function fminsearch was then used to estimate the best ( μ , σ ) pair by minimizing a χ 2 -like error metric given by M 2 = ∑ θ min θ = 60 [ I exp ( θ ) − I Stheory ( θ ) ] 2 + 10 ∑ θ = 30 θ = 60 [ I exp ( θ ) − I Stheory ( θ ) ] 2 . (3) Because angular scattering is much stronger at smaller values of θ , the second sum was included to boost the influence at the larger angles.

Article Title: Patient-to-Patient Variation of Susceptibility-Induced B 0 Field in Bilateral Breast MRI
Article Snippet: A simplex search algorithm (fminsearch) provided by Matlab (MathWorks, MA) was used for optimization.

Article Title: Gradients in the mammalian cerebellar cortex enable Fourier-like transformation and improve storing capacity
Article Snippet: Other optimization routines such as a simplex [(fminsearch() of Matlab) or a genetic algorithm (ga() of Matlab)] revealed similar results.

Article Title: A Biophysical Model of CRISPR/Cas9 Activity for Rational Design of Genome Editing and Gene Regulation
Article Snippet: To identify a narrow range of best-fit parameter values, model parameterization was performed by using either a simple simplex method (fminsearch) or a Levenberg-Marquardt method (lsqnonlin) in MATLAB to minimize the sum of squared relative errors, followed by a parameter sensitivity analysis and visual comparisons to more precisely identify best-fit model parameters.

Article Title: Modeling of the water absorption during the steeping of yellow peas
Article Snippet: The aim of this work was to develop a model of the water uptake by yellow peas during the steeping step of a malting process to serve for the selection of most appropriate time–temperature conditions.. Two empirical (Peleg and lag phase equations) and three mechanistic models (Fick law analytical solution with and without consideration of the surface resistance to mass transfer and a comprehensive model coupling mass transfer and mechanical deformation) were developed.. The coupled mass transfer and mechanical deformation model (RMSE = 0.025, R2 = 0.98), the Peleg equation (RMSE = 0.025, R2 = 0.97) and Fick law analytical solution with consideration of the surface resistance to mass transfer (RMSE = 0.026, R2 = 0.97) provided the best description of the water uptake of peas measured at five temperatures.

Article Title: Dynamic modeling of syngas fermentation in a continuous stirred‐tank reactor: Multi‐response parameter estimation and process optimization
Article Snippet: The MATLAB function fminsearch applies Simplex Algorithm for unconstrained multi-variable problems, but in the present study the parameters are constrained as shown in Table S2.

Article Title: Optimized sampling for view interpolation in light fields using local dictionaries
Article Snippet: We present an angular superresolution method for light fields captured with a sparse camera array.. Our method uses local dictionaries extracted from a sampling mask for upsampling a sparse light field to a dense light field by applying compressed sensing reconstruction.. We derive optimal sampling masks by minimizing the coherence for representative global dictionaries.
