Hi,

I have an 4D array of size 31*229*374*80 (id, y, x, z) which I pass as input to a mex function. This is read as a 1D array in the mex function and is repoted as being a 229* 11594*80 (11594 = 31*374). I am confused about how to get the value of a given index in the function now. Suppose I want to get the value of array number 10 and inexes 50, 100, 40 in the 1D array in the mex function. How do I get to the correct address in the array ?

Thanks in advance,

Kamran

Please give more details and show your code. All variables retain their sizes (dimensions) when passed into a mex routine. If you are seeing a different size then you are not coding properly, or the variable is not the size you think it is.
