I can't figure out why x_array(i) isn't being assigned as a variable

if true
  % code
end
clear;
clc;
i=1
angle_radians = 0;
num = input('Enter the number of terms to calculate(20 to 100):');
while  num <= 19 || num > 100
  if num <= 19
      fprintf('You entered: %s, too few terms\n',num);
  end
  if num > 100
      fprintf('You entered: %s, too many terms\n', num);
  end
  num = input('Enter the number of terms to calculate(20 to 100):');
  while i:num
      x_array(i) = angle_radians;
      y_array(i) = sine_Taylor(angle_radians_radians,terms);
      i = i + 1
  end
end
plot(x_array(i),y_array(i))
fprintf('Sine function from Taylor series in Fig. 1\n')
fprintf('Sine Taylor series vs. sin Matlab function in Fig. 2\n')
fprintf('Program ended\n')

I can’t run your code. Changing the nested while condition to:

while i <= num

might be a solution.
