Calling Sequence

[pix_arr_out]=multi_pixarr(pix_arr_in, coef)

Parameters

• pix_arr_in : the input pixel array.
• coef : the coefficient to multiply
• pix_arr_out : the output pixel array.

Description

multiply the elements of a pixel array.

Examples

	dim=100;arr=[];
	for i=1:dim
		for j=1:dim
			sgn=i*j;
			arr=[arr,sgn];
		end
	end  
	pix_arr=pixel_array(dim);
	pix_arr_1=set_pix_arr_data(pix_arr,arr);
