Unrecognized function or variable

I'm doing a Dijkstra's Algorithm - Matlab Formulation. But when I run the code, it appears this error:

Unrecognized function or variable 'lenght'.

Error in dijkstra (line 5)

N = lenght(map);

Error in practice (line 2)

distances = dijkstra(map,1)

And I don't know why. It's worth mentioning that I have two windows or scripts, one where is my code and the definition of the functions, and the other one where I declare my data.

function distances = dijkstra(map,startingpoint)

N = lenght(map);
distances(1:N) = Inf;

visited(1:N) = 0;

distances(startingpoint) = 0;

while sum(visited) < N
    %Find unvisited nodes
    candidates(1:N) = Inf;
    for index = 1:N
        if visited(index) == 0
            candidates(index) = distances(index);
        end
    end
    %Find the one with the smallest distance value
    [currentDistance, currentPoint] = min(candidates);
    
    %Given the distance to the current point, update the distances to all
    %its neighbors if the new distance will be smaller
    for index = 1:N
        newDistance = currentDistance + map(currentPoint, index);
        if newDistance < distances(index)
            distances(index) = newDistance;
        end 
    end 
    
    %Mark the current node as visited
    visited(currentPoint) = 1;
    
    
end    

%The other window, has the following code:
map = xlsread('map.xlsx');
distances = dijkstra(map,1)

[lol]

This is the error that prints (the window where I have declare the file and run the program is name "practice":

>> practice
