getting error as Matrix dimensions must agree.
显示 更早的评论
Hi all,
i am trying to solve the above equation in matlab, but i am getting an error as matrix dimensions must agree while solving the code
any suggestions and thanks in advance
clc;
clear;
format short;
ro = 17.5; % op.ra
R = 65; b= 1.225*ro; % radius of cylinder
r = b:5:R; % let us divdie r values into two section upto b point
ro_bar= ro/R; %dimensionless variable
x1 = r/R; % set of point from radius and b point
b1 = ro:0.45:b;
r_b1 = b1/R; % set of points from b point to op.ra
alp= asind(ro/R);
% let us make two divisions
func1 = @(r)((r.^3)./(sqrt((x1).^2) - ((ro_bar).^2) - (((x1).^6).*(1-((ro_bar).^2)))));
i = zeros(size(x1));
for c = 1:length(x1)
i(c) = integral(func1,0,x1(c));
end

Can you show your integral equation in MATLAB form? You can attach it as an image.
