This example demonstrates a way to have different x and y ranges. The command linspace a,b,N gives N points between a and b so linespace 0. It provides visualization, image manipulation, and plotting as well as parallel programming. Sign up or log in Sign up using Google. What is the best open source alternative for matlab. Create a “grid” in the xy-plane for the domain using the command meshgrid Calculate z for the surface, using component-wise computations Plot the surface.
Sometimes I use axis limets to make the plot look nicer eliminates the unneeded white area’s ; for this set of data I could use xlim [6 11] and ylim [2 6]. This has a lot of stuff; read the contents carefully! Well, matlab stands for matrixlaboratory and this site is dedicated to working with matrices, vectors, arrays.

Z plot is a free plotting software that allows you to visualize a pllt of mathematical functions frreemat curves. Hm, as far as i can tell, it should give you an error since Z has to be a matrix and you’ve only defined a vector.
Vectorized fprintf, sprintf, fscanf, sscanf functions. Your example only really defines a curve, I’m not sure how you go from that to a surface. Basically, I have 3 parameters, x, y ,z which I have the values from experimental datas and I would like to plot them out.
