MATLAB graphics defines a surface by the z-coordinates of points above a rectangular grid in the x-y plane. The plot is formed by joining adjacent points with straight lines. Surface plots are useful for visualizing matrices that are too large to display in numerical form and for graphing functions of two variables. MATLAB can create different forms of surface plots. Mesh plots are wire-frame surfaces that color only the lines connecting the defining points. Surface plots display both the connecting lines and the faces of the surface in color. | |

You’ve heard the promises of dаta: if you just unlock the hidden insights, you can win an unfair game. But for people at most companies, friction prevents data from flowing effortlessly into decisions. Technology alone won’t make the connection for you. Neither will finding more data; you’ve already got plenty. To connect data with decisions, you’ll need to reverse the way data flows through all your systems and decisions. If you’re a business decision-maker – a CEO, CIO, or CxO – you’ll see the connection between a data strategy and the thousands of decisions people in your company make every day. If you’re a data worker, you’ll see how your work changes the direction of a company. And if you’re an analyst – someone who bridges the gap between top-level decision makers and what’s really happening in the business – you’ll find a new vision of how to use data to transform your job and your company. | |
