MATLAB: Error sign not valid

errorfunctionMATLAB

I have this function

n = 1;
Product = 1;
while( Product < N )
{
Product = Product * (2*n);
n = n + 1;
}
end

and this error keeps on popping up Error: File: Untitled5.m Line: 5 Column: 9 The expression to the left of the equals sign is not a valid target for an assignment.

That's not valid MATLAB syntax. In particular, the curly brackets shouldn't enclose the while loop. (You also used capital N where you had been using small n.)

Does this do what you intend?

n = 1;
Product = 1;
while( Product < n )
Product = Product * (2*n);
n = n + 1;
end

MATLAB: How to save matrix created in each iteration

One of ways

n=1;
k=[1 2 3 4;5 6 7 8];
out = zeros([size(k),3]);
while n<4
    k=k*n;
    out(:,:,n) = k;
    n=n+1;
end

MATLAB: While command in matlab

A while statement operates as follows:

while (condition)
{
perform action
}
end

As such, if you were to have a while loop with a condition that your product is less than your maximum N, it will run the loop until the product exceeds N at which point the condition is met.

Within the loop then, you would want to have the number continue to multiply as long as it is running. This would leave you with something as follows:

n = 1;
Product = 1;
while( Product < N )
{
Product = Product * (2*n);
n = n + 1;
}
end

with that you could have some variable that increments every time the while statement goes through in order to count how many iterations occur until you exceed your maximum.
