Question

Given a vector, t, of length n, write down the MATLAB expressions that will correctly compute the following. For this question you don't need to include the whole code, you only need to include a single Matlab expression for each signal.

In(2+ t²)

Answer 1

The MATLAB expression to compute In(2+ t²) for a vector t is log(2 + t.^2), using element-wise squaring and the logarithm function.

Step-by-step explanation:

The student is asked to compute the expression In(2+ t²) in MATLAB, assuming t is a vector of length n. In MATLAB, the operation for squaring each element of a vector is performed element-wise using the .^ operator, and the natural logarithm function is denoted by log. Thus, the MATLAB expression to compute the required signal is log(2 + t.^2).
