Please help with this equation

i have inserted the following equation into matlab, i want values of Z for each value of w from 0.001:1000. but i keep getting a single value only. i will insert my matlab code below, i have converted the names of some values into simple a,b,c,e to make it easy for me to insert the values into matlab. ill insert some pictures what my question.

my matlab code: >> a = 1; t = 1; w = 0.001:1000; b = 10; d = 0.25; c = cos((d*pi)/2); e = w*t; z = sqrt((a.^(2)*e.^(2*d)+2*c*b*a*e.^(d)+b.^2)/(1+2*c*e.^(d)+e.^(2*d)))

z =

    2.5265

>>

You need to completely vectorise your equation, including the division:

z = sqrt((a.^(2)*e.^(2*d)+2*c*b*a*e.^(d)+b.^2)./(1+2*c*e.^(d)+e.^(2*d)));
                                              ↑ ← VECTORISE DIVISION

That should work.

My pleasure.

Since this is homework, type:

lookfor log10

in your Command Window. Click on the result.

You could do the same for ‘plot’ (so lookfor plot). You would then see the documentation on the plot (link) function.
