want to save data from simulink, but receive "The file name is invalid because it does not have the extension ".mdl" or".slx"."

error:The file name 'C:\Users\Jason\Desktop\fangbo.xlsx' is invalid because it does not have the extension ".mdl" or".slx".

my code:

[t_time,x_state,y_out]=sim('C:\Users\Jason\Desktop\fangbo.xlsx',[0,181]);           
filename_time='C:\Users\Jason\Desktop\fangbo.xlsx'; 			
sheet=‘sheet1’；									
position=‘A1’；										
xlsxwrite('C:\Users\Jason\Desktop\fangbo.xlsx',Out1,sheet,B);

what's wrong with my code?how to solve this problem?

HELP!

as matlab tells you, it's the wrong file extension :

[t_time,x_state,y_out]=sim('C:\Users\Jason\Desktop\fangbo.xlsx',[0,181]);

should be

[t_time,x_state,y_out]=sim('C:\Users\Jason\Desktop\fangbo.mdl',[0,181]);

or

[t_time,x_state,y_out]=sim('C:\Users\Jason\Desktop\fangbo.slx',[0,181]);

you should also probably use another file name for saving your data in the excel file - using the same name for simulink and excel is prone to confusion

sim() runs a Simulink simulation. Model name should be *.slx or *.mdl, not *.xlsx.

Variable 'Out1' and 'B' are not defined in your xlswrite() line, not xlsxwrite().

Pay attention to the calling syntax of sim() and xlswrite(). Look at the document for examples.
