Trying to plot a function
显示 更早的评论
I am trying to plot the following function and have the period after "theta_shock", but I am getting an error of "Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters"
theta_shock = 0:90
M = 2
g = 1.4
half_cone = atand((M^2*sind(theta_shock.)-1)/(M^2*(g+cosd(2*theta_shock.))+2))
plot(theta_shock,half_cone)
What am I doing wrong and how do I fix this?

Here is the fixed code:
theta_shock = 0:90;
M = 2;
g = 1.4;
half_cone = atand((M^2*sind(theta_shock)-1)./(M^2*(g+cosd(2*theta_shock))+2));
plot(theta_shock,half_cone)

The source of the error were the fullstops present after theta_shock
Removing them and using the element-wise division for numerator and denominator gave the correct output.
