MATLAB: Where is this startup error coming from

MATLABnonexistantwarning

I'm receiving this error message when I start 2017b (recently installed) but not 2016b (previous version).

_Warning: Name is nonexistent or not a directory: C:\Program Files\MATLAB\R2017b\toolbox\matlab\hds >>_

My startup.m program has not changed and does not refer to that directory.

Hi John!

I suggest you to have a look at the below link:

It addresses a very similar query.

See Importing Data to Root-Level Input Ports. In particular, you need to look at the Configuration Parameters > Data Import/Export > Input parameter.

That:

if true

is not part of the code, right? If it is, then you should be not even able to run the code....

Did you look at the output S? S has two solutions; it is a 2-by-1 one symbolic variable. To turn it into a 2-by-one double value, do:

S = subs(S);

Now use the element-by-element division:

x1=z1./(S*(K1-1)+1);
x2=z2./(S*(K2-1)+1);
x3=z3./(S*(K3-1)+1);
y1=K1*x1;
y2=K2*x2;
y3=K3*x3;
