MATLAB Answers is a great resource for getting help from the MATLAB community. There was a recent question that inspired this video. I took the question to mean, how can I change the color of a line to correspond with a third vector. Here is my answer. Recorded: 12 Aug 2014R...
Some of the key functions include:Gradient:The gradient function in MATLAB computes the numerical Gradient of a vector or scalar function. It is particularly useful when dealing with discrete data. For example:x = linspace(0, 2*pi, 100); y = sin(x); dy_dx = gradient(y, x); ...
First of all, you should know that when I say parameters I mean our vector of theta which is a 2D vector that contains the intercept and slope of our hypothesis line. Now let's start with the partial derivative of our cost function of theta (with respect toθj), that partial derivative...

Evaluate gradients of the solution along the straight line from(x,y)=(-1,-1)to(1,1). Plot the results as a quiver plot by usingquiver. xq = linspace(-1,1,101); yq = xq; [gradx,grady] = evaluateGradient(results,xq,yq); gradx = reshape(gradx,size(xq)); grady = reshape(gra...
The Matlab code, named GFLS262, consists of a 62-line main program, 41-line finite element analysis function, and 48-line sub-functions, enabling the implementation of the GFLS method in 2D scenarios. Additionally, a 111-line function describes an improved mesh generator incorporated in the ...

The initial step is the position on the line of gradients where the first color starts. The endpoint is the ending point of the last color. The intersection of the gradient line with a perpendicular line coming from the box corner, which is in the same quadrant, represents one of these tw...

The process of generate the data can be done in two ways: by user clicking over the top graph, or automatically using the rand built in function of matlab. In the last way a buffer parameter can be set by the user to control how spread the points are. Increasing the value of this ...
