When the 'GradObj' is 'off', then the 'fminunc' calculate the gradient of the parameters need to be optimzed for me. (I suppose the Matlab use finite difference method to get the gradient)... m and b are the slope and intercept of line 1, perSlope and yInt are the slope and intercept of line 2. xIntersection = (yInt - b) / (m - perpSlope); To get the y coordinate of the intersection, we just plug the x coordinate into one of the equations.

Notice the importance of the command ‘hold on’, it avoid that Matlab create a new figure window for a new “drawing” You can also add another correlation (with var1) by simply replacing the how to go up 2 lines in python refline(m,b) adds a reference line with slope m and intercept b to the current axes. example refline( coeffs ) adds the line defined by the elements of the vector coeffs to the figure.

## How To Get Gradient Of Line Line In Matlab

to detect the edges of the circle in the image, and then compute the gradient vector field due to the circle in the image. obviously, assigning u=x and v=y will only give me the vector field of a straight line - so bascially, I want to embed the gradient of the image into the vectors u and v. How do I do this?

- This is a horizontal line with color gradient going from left to right (in the direction of the sample points). Is there a way to have a gradient going from top to bottom? (if the line is tilted, then the gradient would be still perpendicular to that line). The effect should look like the line …
