Symbolic Math in Matlab Matlab has a powerful symbolic math ability. Rather than making calculations on known numbers‚ we can make calculations on symbolic expressions. For example‚ what is the limit as x approaches inf of 1 + 1/2^1 + 1/2^2 + 1/2^3...+1/2^n ? Matlab can tell us. What is the integral of x^3 for any x? Matlab can tell us. Symbolic Math in Matlab Matlab allows you to create symbolic math expressions. This is useful when you don’t want to immediately compute an answer‚ or when

extraneous variables by using random assignment to experimental conditions and sometimes also by incorporating direct control and/or blocking into the design of the experiment. Each of these strategies—random assignment‚ direct control‚ and blocking—is described as follows; A researcher can directly control some extraneous variables. In the calculus test example‚ the textbook used is an extraneous variable because part of the differences in test results might be attributed to this variable. We could
