Trying to 'randomly pick a word' by using Matlab. I set up a column with numerical values 1-4, then I chose a random number generator to pick a number. But now, (the part I need help with) I am trying to set the numerical value to a word associated with the number, I am new at this; please help if you can.
k=0;
cols=['WORD'];
WORD=0;
for i=1
for j=1:4
k=k+1;
word(j,i)=k;
used(j,i)=0;
end
end
count=0;
gameplay=1;
while gameplay
pick=0;
while pick==0
pick_word=ceil(rand()*4);
wordplayed=word(pick_word);
if pick_word==1
wo=disp('skate');
elseif pick_word==2
wo=disp('place');
elseif pick_word==3
wo=disp('sleep');
elseif pick_work==4
wo=disp('lefty');
end
if used(pick_word)==0
used(pick_word)=wordplayed;
pick=1;
count=count+1;
end
end
if pick_word==1
WORD=WORD+1;
end
end

Instead of
wo = disp('skate');
you need
wo = 'skate';
You're mixing up the process of printing something in a window (which is what the disp function does) with a assigning a value to a variable.
I think you may have some other misconceptions too - for example "I am trying to set the numerical value to a word" doesn't make sense - and I think it would be a good investment of time to go over the "getting started" material in the documentation again.

Okay, thanks.
Let me try to make sense of my qoute...
"...I am trying to set the numerical value to a word..."
What I mean is, when the program I create, picks one of the random numbers, I want the word I have assigned to the number to be picked. (i.e. random number generates 1-the word picked should be skate; loop back to start, random number generates 3-the word picked should be sleep). Maybe I am making sense, but I will go back to the "getting started" material and see if that helps me.
Thank you again for your input.

W = {'skate','place','sleep','lefty'};
r = randperm(length(W));
W(r)
