Following the author's step-by-step instructions, here are just a few of the calculations you learn to perform: Use worksheet functions to work with matrices Find roots of equations and solve systems of simultaneous equations Solve ordinary differential equations and partial differential equations Perform linear and non-linear regression Use random numbers and the Monte Carlo method This text is loaded with examples ranging from very basic to highly sophisticated solutions. More than 100 end-of-chapter problems help you test and put your knowledge to practice solving real-world problems. Answers and explanatory notes for most of the problems are provided in an appendix. The CD-ROM that accompanies this text provides several useful features: All the spreadsheets, charts, and VBA code needed to perform the examples from the text Solutions to most of the end-of-chapter problems An add-in workbook with more than twenty custom functions This text does not require any background in programming, so it is suitable for both undergraduate and graduate courses. Moreover, practitioners in science and engineering will find that this guide saves hours of time by enabling them to perform most of their calculations with one familiar spreadsheet package




Up Up and Array!


Book Description

Understand the power of dynamic arrays: a single formula can generate new and vastly more efficient spreadsheet possibilities. This book introduces spreadsheet users to dynamic array functions in Microsoft Excel 365, defines and details the distinctive ways in which they work, and shows how they can be applied to a wide swath of data-analytic tasks. While array formulas and functions have long held a place in the spreadsheet toolbox (although, for many of us, shunted to an obscure corner), the dynamic array engine offers a more user-friendly and intelligible set of means for manipulating spreadsheet data in the array mode. The single-formula, multi-cell capability of dynamic arrays has been extended to nearly all existing spreadsheet functions, offering a new, default way of working. As a result, many tasks can now be executed with dynamic arrays without having to resort to the new functions at all. After defining arrays and dynamic array formulas, this book helps you examine the dynamic array property of lifting and how it impacts the formulas, including those written with existing functions. Plenty of illustrations and formulas along the way help you get comfortable using them. From there, you will learn Excel 365's new dynamic functions, including the 14 currently in rollout, each accompanied by instructive examples. In many cases, the examples demonstrate how the new functions can work with long-available functions, such as MID, IF, COUNTIF, etc., which now also boast dynamic array functionality. What You Will Learn Unlock the dynamic array potential in Microsoft Excel Apply dynamic array functions and confidently direct them to real-world spreadsheet tasks Know the distinctive ways in which arrays work and can be applied to numerous data-analytic tasks.
