+function errmsg = fminimaxCheckdims ( funname , var , varname , ivar , matdims )
+ // Generates an error if the variable has not the required size.
+ //
+ // Calling Sequence
+ // errmsg = fminimaxCheckdims ( funname , var , varname , ivar , matdims )
+ //
+ // Parameters
+ // funname : a 1 x 1 matrix of strings, the name of the calling function.
+ // var : a 1 x 1 matrix of valid Scilab data type, the variable
+ // varname : a 1 x 1 matrix of string, the name of the variable
+ // ivar : a 1 x 1 matrix of floating point integers, the index of the input argument in the calling sequence
+ // matdims : 1 x 2 matrix of floating point integers, the number of rows, columns for the variable #ivar
+ // errmsg : a 1 x 1 matrix of strings, the error message. If there was no error, the error message is the empty matrix.
+ //
+ // Description
+ // This function is designed to be used to design functions where
+ // the input argument has a known shape.
+ // This function cannot be use when var is a function, or more
+ // generally, for any input argument for which the size function
+ // does not work.
+ // Last update : 05/08/2010.
+ //
+ // Examples
+ // // The function takes a 2 x 3 matrix of doubles.
+ // function y = myfunction ( x )
+ // fminimaxCheckdims ( "myfunction" , x , "x" , 1 , [2 3] )
+ // y = x
+ // endfunction
+ // // Calling sequences which work
+ // y = myfunction ( ones(2,3) )
+ // y = myfunction ( zeros(2,3) )
+ // // Calling sequences which generate an error
+ // y = myfunction ( ones(1,3) )
+ // y = myfunction ( zeros(2,4) )
