I run this identity test and get this response....what am I doing wrong

function result = singularitytest(A)
   d = det(A);
   c = cond(d) <= 1e-10;
end

Output argument "result" (and maybe others) not assigned during call to "singularitytest".

[Stephen23]

You define a function with one output argument result:

function result = singularitytest(A)

Inside the function you define several variables, but you do not define result anywhere. Thus the error: if you do not tell MATLAB what result is, how do you expect it to return anything?

Perhaps you meant to do this:

function result = singularitytest(A)
   d = det(A);
   result = cond(d) <= 1e-10;
end
