Derive a state-space representation and write a matlab code to integrate a nonlinear differential equations x = f(x) x + 4(x^2 - 1)x + x = 0; x(0) = 0.75, x(0) = 0 x + 2xx + x = 0; x(0) = 1.0, x(0) = 0 for each equation provide following plots: x_1 vs. t, x_2 vs. t and x_2 vs. x_1

Sarah is having a hard time finding a template for her advertising business that she may be able to use at a later date and also make it available to her colleagues

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
