How to pass double[][] into a method call?

Question

Hi I am trying to init an object with a double value in the format double filter[3][3]; but i keep getting the following error.

cannot convert \'double[3][3]\' to \'

Answer 1

you are passing as a parameter a double 2d array(double[][]) when your method signature asks for a double (a primitive like 34.2). set the method declaration to

- (id)initWithMatrix:(double*) matrix;

this passes a pointer to your array (2d) to the method. edit: missed a semicolon.
