We can use the following formulas: T=v|v|,B=v×a|v×a|,N=B×T, where v(t)=r′(t), and a(t)=r′′(t). We'll write the velocity and acceleration vector fields in terms of the parameter t whenever the are defined, and we'll evaluate them...
Question: Find the vector and point that were used to define the line given by the system of equations: {eq}x = 5,\ \ y = t-4,\ \ z = -2-t {/eq}. Equation of a Line: Consider a point on a line, {eq}P_0 = (x_0, y_0,z_...
manifold nearest the origin of coordinates are analysed in three formulations: maximization of the set of zero components, Pareto-minimization of the absolute values of the components of the unknown vector, and minimization of special penalty functions with an absolute minimum at the origin of ...

dateVector = datetime(time_cell,'InputFormat', timeFormat); dateVector.Format = timeFormat The last line changes the format used to display the date vector to match the format as it was imported so that the display of the dateVector should match exactly what you see in time_cell. ...
value is the element we want to insert. Syntax for Inserting Multiple Elements vector.insert(position, start_iterator, end_iterator);Where,position is the index, where we want to insert the element.start_iterator is an iterator that points to the first element to be inserted.end_iterator is ...
What was the suitable command for replacing data points at given field indices with the average of the values before and after ? My data are one time vector and multiple parameter vector related to this time vector. With filloutliers command, I get an ind...
【题目】The position vector of a set of points are given by$$ r = \begin{pmatrix} 2 \\ - 1 \end{pmatrix} + \lambd a \begin{pmatrix} 2 \\ 4 \end{pmatrix} $$where λ is a parameter that can take any value and A is the point (2, -1).Find the position vectors of ...
