MATLAB: How to open the older models saved by Simulink 2.0 in “.m” file format in Simulink 5.0 (R13) that only accepts “.mdl” format

.mfilesmdloldersimulinkversion

How can I open my older models saved by Simulink 2.0 in ".m" file format in Simulink 5.0 (R13) that only accepts ".mdl" format?

I have a model saved by Simulink 2.0 and I would like to work on the model in Simulink 5.0 (R13).

To open an ".m" format model in a current version of Simulink:

1) Open the ".m" format model in Simulink 2.2 (R10)

2) Use the SLUPDATE command to replace blocks from a previous release with newer ones. After the SLUPDATE, the model is saved as ".mdl" format under "File -> Save As".

3) Open the model in Simulink 3.0.1 (R11.1)

4) Update the model using the SLUPDATE command and saved in ".mdl" format. This procedure is repeated until the desired Simulink version is reached.

This is expected behavior. The function SLSAVEAS converts an existing Simulink 5.0 (R13) model into an older version. Since the model has not yet been saved in Simulink 5.0 (R13), there is no model to convert and you will receive the above error. To avoid this error, you must first save your model in Simulink 5.0 (R13) and then save it as an older version.

x=[1,2,3]
y=[4,5,6]
z=[7,8,9]
FileName='results';
FID = fopen(FileName, 'w');
if FID < 0, error('Cannot open file'); end
data = [z', x', y'];
fprintf(FID, 's\n%g\n%g\n', 100,1);
fprintf(FID, '%g %g %g\n', data');
fclose(FID);
