Add text column to data

Dear whom regards, I'd like to add a text column (on the left side) to my given data (10x3 double) generated through my loop. So, currently I have the following format of data

1 1 1
1 1 2
1 1 3
1 1 4
1 2 1
1 3 1...

So, my desired data format is

    COORDINATE 1 1 1
    COORDINATE 1 1 2
    COORDINATE 1 1 3
    COORDINATE 1 1 4
    COORDINATE 1 2 1
    COORDINATE 1 3 1...

Any tips would be grateful. K-Won

A=[1 1 4
1 2 1
1 3 1]
B=repmat({'coordinate'},size(A,1),1)
out=[B num2cell(A)]
