n = 10;
A =zeros(1,n);
count=1;
while i==1 && j==1:n;
count=count+1;
A(i,j)=count;
end
display(A)
trying to get this to display A=[1 2 3 4 5 6 7 8 9 10] using exactly 1 while loop.

while i==1 && j==1:n;
j==1:n is a vector comparison, with a vector result (length 10). You cannot use a vector together with the && operator.
Also, your while loop does not change i or j, so your loop would be infinite if it was accepted at all.

variable = initial_value;
while variable <= final_value
do something with variable
variable = variable + increment;
end

OP was asking for one liner.
Here is the shorter verion, it worked on my PC.
n=10;A=[];k=1;while k <=n,A=cat(2,A,k),k=k+1;end

You didn't format this as code, and it actually performs worse than your other answer, because it dynamically grows the array. Other than that it is identical to your other answer. What would be the benefit? Compressing code into a one-liner doesn't usually improve code readibility and doesn't change performance.

The poster asked for exactly one while loop, but did not ask for a one-liner.
