translating from idl to matlab

Hi I'm trying to translate some codes i have from IDL to matlab.

the idl codes are

lineflat = reform(flatsub(*,cutline))

this is my understanding in matlab

lineflat = reshape(flatsub,cutline,:);

however i get an error that ":" that tells me "Undefined function or variable 'reshape'"

if i change the : to [] it works? but im not sure if its the same function flatsub is a variable, and cutline is a number.

Thanks

If you are trying to call the MATLAB built-in function 'reshape', you need to follow the correct syntax in order for it to work. As can be seen from the ' reshape ' documentation, you can specify a single dimension size of '[]' to have the dimension size automatically calculated. On the other hand, ':' is not a valid input for the 'reshape' function.
