    <p>I want to do a seam carving in an image using Matlab.</p> <p>If i do it using only scripts and not by calling the function,it works.The problem comes when i make the script as a function and try to call it</p> <p>The code i use</p> <p><strong>Final Script:</strong> Its the script i use to call the function over and over so i get the result</p> <pre><code>clear all; close all; %Image = 'mall.jpg'; Image_Array = imread('mall.jpg'); %We keep the dimension of the image array [Row_Count,Column_Count,Colour] = size(Image_Array); Image = double(Image_Array)/255; Image = rgb2gray(Image); for i = 1 : 10 [Image_Array,Row_Count,Column_Count]=Vertical_Seam(Image_Array,Row_Count,Column_Count); imshow(Image_Array); end </code></pre> <p><strong>Vertical Seam:</strong> its the script i use to do the work of seaming.This is the file i would like to make it a function and call it in the Finalscript but i dont know how(You will notice that i tried to make a fucntion but as it didnt work i put it inside % )</p> <pre><code>%function [Final_Image,Row_Count,Column_Count] = Vertical_Seam(Image_Array,Row_Count,Column_Count) Image_Array = imread('mall.jpg');

    1. COthis is a lot of uncommented code. What error you get? Try to break down your code a bit. And I don't really get, do you want to call the function directly from the editor? or do you want to use the script above and call the function from the script? Why do you have congruent code outside and inside the function?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
