WebApr 15, 2024 · Image segmentation has been one of the most active research areas in the last decade. The traditional multi-level thresholding techniques are effective for bi-level thresholding because of their resilience, simplicity, accuracy, and low convergence time, but these traditional techniques are not effective in determining the optimal multi-level … WebSep 10, 2013 · As stated on the linprog function reference page: x = linprog (f,A,b,Aeq,beq,lb,ub,x0) sets the starting point to x0. linprog uses x0 only with the active-set algorithm. linprog ignores x0 with the interior-point and simplex algorithms. However, 48 variables, or even 100, is not a big problem. WebI would like to use the POLYFIT function or the Curve Fitting Toolbox to impose linear constraints on fitted curves to force them to pass through specific points like the origin. fisher plow electric hydraulic pump
