1. This is a question to familiarize yourself with Matlab and some of it operators and calling conventions, as well as some general evaluation rules. Perform each of the following by writing a function that performs all the following questions and returns the results in a structure. How you import the data is up to you. The variable b needs to be recast as a numeric array. Use search to determine how to convert a string variable to its numeric value. = to in steps of 0.5 [a] xy [b] yx [c] x."y and y.x Are the results equivalent? [d] If x/y is equivalent to xy1 where the superscript 1 denotes matrix inverse, what is the determinant of y ? Return the determinant of y and "equal" if equal, "not equal" if not. [e] xy where the apostrophe operator takes the transpose, and the bars denote determinant. [f] (ab)(x+y)cc(x2+y2)/1e7 The brackets denote the determinant. [g] The magnitude and phase (in degrees) of the result in [f]. [h]Z=(ei3P/4+eie)2 Plot this result rather than printing it out. Absolute value bars denote magnitude
