Making a matrix of fibonacci values and the corresponding number of elements to get 5702887? Using a while loop I am not sure where to begin. I was given that the output must be 5702887 and there should be 26-39 elements in the vector and that I must use a while loop

Do you know how to calculate Fibonacci numbers? Do you know how to write a while loop? Do you know how to iteratively assign values to the elements of a vector in a loop? That is where to begin.

Yes I know how to calculate them and how a while loop works, I am just confused about the programming

在 MATLAB Online 中打开

last_generated = 0;
while last_generated < 5702887
  generate another one
  last_generated = generated value
end

Look at this example:

results = []; currentvalue = 0;
while currentvalue < 5
  thisvalue = rand();
  results(end+1) = thisvalue;
  currentvalue = currentvalue + thisvalue;
end
length(results)
