gDrawLite vs CloudLabs Graphs and Matrices

Move! Move! It moves! You can draw and move your graphs! Setting invariables in the formula and changing the value, you can move your graphs freely! AMAZINGLY MANY KINDS OF GRAPHS! You can draw many kinds of graphs by setting function such as y=f(x), x=f(y), x=f(t) and y=g(t), f(x,y)=0, pole equation. (In the Lite version, we support only "y=f(x)" and command "Line") MOVE GRAPHS! This is the greatest feature of this app! We prepared "m" as an invariable. You can change the value continuously and see the graph moving. Using this feature, you can see many interesting moves, such as simple oscillation, cycloid curve, synthesis of waves. ORIGINAL KEYBOARD! We prepared the original keyboard specialized for mathematical formulas. You can type mathematical formulas very easily. SEE MANY GRAPHS SIMULTANEOUSLY! You can set unlimited number of graphs and see them simultaneously. VERY CONVENIENT TOOL "com". By using this, you can draw line segments, circles, points and texts very easily. For example, you can draw a line segments by setting the starting point and the end point. MANY INTERESTING SAMPLES! You can load many interesting samples from “Load SampleCom”. They are not only interesting, but also help you to master this app. TAKE A PHOTO OF YOUR GRAPH! You easily take a photo of your graph by pushing “photo button”.

In this practice, you will use matrices to describe the flow of gas in some pipes. You need to use the graph to construct the incidence matrix and calculate the square matrix. To do so, you will use matrix multiplications. This type of multiplication is simple, as the matrix is composed of ones and zeros.
