Solving Linear System and Linear Optimization Equations Using Microsoft Excel and MATLAB In the previous instalment on linear systems we saw that Excel can easily invert a modest-sized matrix and find solutions to a set of simultaneous linear equations. In the real world, a place I allude to frequently and try to avoid as much as […]

How to Solve Linear Equations in Excel Using the MINVERSE and MMULT Functions Systems of linear equations pop up everywhere you look. Small retail shops want to maximize the profit from the distribution of goods taking up limited shelf space. Chemists need to balance constituents of a complex reaction. Economists are compelled to build models; […]

In the previous segment, we saw how to write DAX statements in Excel to query Power Pivot Data. In this segment, we will take a first look at the SUMMARIZE function. While the DAX queries discussed here could be executed in the Management Studio against an Analysis Services tabular mode database, here we will be […]
