Populating column Vector containing 200 17's followed by 300 -11's

I am having extreme trouble trying to figure out how to do a homework question.

The question is asking:

Create a 500-element Column vector P17M11 containing two hundred number seventeens followed by three hundred number negative elevens.

repmat, mabye???

Could you possibly elaborate on how to use repmat to do this? I tried working with it for an hour and i have gotten no where.

[Star Strider]

What have you done with repmat? What have you tried?

It replicates the first argument in a matrix whose size is given by the second (#rows) and third (#columns) arguments.

Another option is the ones function, with scalar multiplication.

The best i was able to do was Replicate only 1 number.

I tried doing P17M11 = repmat(17,1,200);

I searched and i don't know what else i can add to it to add the three hundred -11 after it.

[Star Strider]

Do the same thing with -11, then concatenate the two vectors.

Thanks Star Strider. I was able to figure it out. I'm new to this language and didn't realize it was that simple :)
