Good book. It really goes into detail. The MATLAB code does not work due to missing functions "unitr" and "crossr".

Errors in the MATLAB code, Antenna Engineering Using Physical Optics

There are errors in the MATLAB code files po09b, po13c, po15d, and po17b, most resulting from calls to previous versions of 3 m-file functions:

incorrect name-----------------correct name
unitr-------------------------norm01
crossr------------------------cross01
vlenr-------------------------length01

These errors can be corrected by making the following changes:

1. on m-file po09b, listed in pages 147-148 of the text, 4 lines must be changed:

line 22 is:
ut2=ones(Na,1)*unitr(crossr(un0,[1 0 0]));
but should be:
ut2=ones(Na,1)*norm01(cross01(un0,[1 0 0]));

line 24 is:
ut1=crossr(ut2,un0);
but should be:
ut1=cross01(ut2,un0);

line 49 is:
urs=unitr([rs zeros(Na,1)]);
but should be:
urs=norm01([rs-ones(size(DSa))*r0]);

line 50 is:
ups=crossr(uns,urs);
but should be:
ups=cross01(uns,urs);

2. on m-file po13c, listed in pages 202-203 of the text, 3 lines must be changed:

line 59 is:
alr=atan(2*Fl./vlenr(rr));
but should be:
alr=atan(2*Fl./length01(rr-rr(:,3)*[0 0 1]));

line 62 is:
u2r=unitr(crossr(unr,ones(Nr,1)*[1 0 0]));
but should be:
u2r=norm01(cross01(unr,ones(Nr,1)*[1 0 0]));

line 63 is:
u1r=crossr(u2r,unr);
but should be:
u1r=cross01(u2r,unr);

3. on m-file po15d, listed on pages 222-224 of the text, 1 line must be changed:

line 26 is:
u2bf=unitr(cross01(unbf,[1 0 0]));

but should be:
u2bf=norm01(cross01(unbf,[1 0 0]));

4. on m-file po15e, listed on pages 222-224 of the text, 1 line must be changed:

line 18 is:
EscJ=-Z0*cross01(ut(nb,:),HscJ); % source E field
HscM=1/Z0*cross01(ut(nb,:),EscM); % source E field
but should be:
EscJ=-Z0*cross01(unb(nb,:),HscJ); % source E field
HscM=1/Z0*cross01(unb(nb,:),EscM); % source E field

5. on m-file po17b, listed on pages 254-257 of the text, 2 lines must be changed:

line 24 is:
u2c1=unitr(cross01(unc1,[1 0 0]));
but should be:
u2c1=norm01(cross01(unc1,[1 0 0]));

line 64 is:
u2c2=unitr(cross01(unc2,[1 0 0]));
but should be:
u2c2=norm01(cross01(unc2,[1 0 0]));
