Error using mex on c file

Hi there,

I am having difficulty using the mex command on a file and I was hoping I could get some advice from you learned individuals. Whenever I use the command

mex ffmygrid.c

I get the following errors:

ffmygrid.c 
ffmygrid.c(49) : error C2059: syntax error : 'type' 
ffmygrid.c(70) : warning C4305: 'initializing' : truncation from 'double' to 'float'

    C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: Compile of 'ffmygrid.c' failed. 

Error using mex (line 206)
Unable to complete successfully.

Could anyone kindly set me on the path to correct this?

I have Windows SDK 7.1 installed and am running Windows 8. I am able to mex the MATLAB sample file timestwo.c so it's not a problem there...

Any help would be greatly appreciated.

Thank you,

Paul

What do you have on line#49? Everything else is warnings that you can fix with explicit casts.
