Right, if you have in C

    typedef struct {
        const char* name;
        float value;
    } S;

    S s = {"hello", 3.14},

    printf("%s = %f\n",, s.value);

Then in Octave you can do, = "hello";
    s.value = single(3.14) ## You wanted single, not double, right?

    printf("%s = %f\n",, s.value);

amongst other possible syntaxes for defining a struct.

Struct arrays are similar in Octave and C too, except that Octave
allows a different way of indexing struct arrays that C doesn't.
