Undefined function or variable 't_x'. The first assignment to a local variable determines its class.

Hi all, I am trying to run this programm through Matlab function in simulink, but am getting following error.

Undefined function or variable 't_x'. The first assignment to a local variable determines its class. Function 'A_star.m' (#258.1132.1135), line 31, column 1: "t_x" Launch diagnostic report.

Component:MATLAB Function | Category:Coder error

Undefined function or variable 't_y'. The first assignment to a local variable determines its class. Function 'A_star.m' (#258.1155.1158), line 32, column 1: "t_y" Launch diagnostic report.

Can anyone help me out.

Thank You.

Hello Madhan ravi,

following is the picture of model. In this simulink model I am trying to run above algorithm, for first iteration I need to give some input as shown in above script. in tx,ty,....data will be stored after all iteration. It is working matlab (script) but not in simulink. My mail id is [e-mail]. Is that possible to contact you.

Thank You.

Try initializing the variable t_x before assigning cur.x to it.

t_x = zeros(len,1);
t_x(t_count)=cur.x;
