Hello, I am currently in the process of running something in cmd via matlab. I want to run the porgramm compose for a certain file.
The below line runs perfectly in cmd without any problem.
"C:\Program Files\Altair\2025\Compose2025\Compose_Console.bat" -e "filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" -f "C:/Users/pantm/OneDrive/Desktop/get_stress.oml"
[Inserted commands in edit mode for clearer reading, editing...dpb]
"C:\Program Files\Altair\2025\Compose2025\Compose_Console.bat" -e "filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" -f "C:/Users/pantm/OneDrive/Desktop/get_stress.oml"
When i run this from matlab system("C:\Program Files\Altair\2025\Compose2025\Compose_Console.bat" -e "filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" -f "C:/Users/pantm/OneDrive/Desktop/get_stress.oml") it doesnt work, giving these errors Syntax error at line number 1 near character position 1
Error: 'filePath' is not defined at line number 17 in file get_stress.oml
system("C:\Program Files\Altair\2025\Compose2025\Compose_Console.bat" -e "filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" -f "C:/Users/pantm/OneDrive/Desktop/get_stress.oml")
Syntax error at line number 1 near character position 1
Error: 'filePath' is not defined at line number 17 in file get_stress.oml
I think its a Syntax error in this and its about these ".
After I fix this problem I want to be able to define this middle part ("filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" ) with something like sprintf so it changes dynamically.
"filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d"

system("C:\Program Files\Altair\2025\Compose2025\Compose_Console.bat" -e "filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" -f "C:/Users/pantm/OneDrive/Desktop/get_stress.oml")
% ^ ^
You start and end a string literal, and then you have -e which would try to subtract a variable named e
You need
system('"C:\Program Files\Altair\2025\Compose2025\Compose_Console.bat" -e "filePath=C:/Users/pantm/OneDrive/Desktop/TEST_LCA_doublelane_0.h3d" -f "C:/Users/pantm/OneDrive/Desktop/get_stress.oml"')
