I want to pass control to other section of code if certain condition becomes true something like this we do in C, code snippet attached for reference.

for k = ele_search_start_edx : ele_search_end_idx
    if data(k) =='C' && data(k+1) == '='
        Element_arr(n) = extraxtBetween(data(ele_search_start_idx : ele_search_end_idx),['=','{',' '],['}',' ','Q'])
        n= n+1;
        goto next_node_search_function
    elseif data(k) == 'N'
        Element_arr(n) = extractBetween(data(ele_search_start_idx1 : ele_search_end_idx1),['=','{',' '],[' ','}'])  
        n= n+1;
        goto next_node_search_function
    elseif data(k) =='L' && data(k+1) == '='
        Element_arr(n) = extraxtBetween(data(ele_search_start_idx : ele_search_end_idx),['=','{',' '],['}',' ','Q'])
        n= n+1;
        goto next_node_search_function
    end
end

No, there is no GOTO in Matlab and it should be avoided strictly in good code.

Maybe:

function YourFunc
n = 123;  % ???
for k = ele_search_start_edx : ele_search_end_idx
    if data(k) =='C' && data(k+1) == '='
        Element_arr(n) = extraxtBetween(data(ele_search_start_idx : ele_search_end_idx),['=','{',' '],['}',' ','Q'])
        break;
    elseif data(k) == 'N'
        Element_arr(n) = extractBetween(data(ele_search_start_idx1 : ele_search_end_idx1),['=','{',' '],[' ','}'])  
        break;
    elseif data(k) =='L' && data(k+1) == '='
        Element_arr(n) = extraxtBetween(data(ele_search_start_idx : ele_search_end_idx),['=','{',' '],['}',' ','Q'])
        break
    end
end
next_node_search_function(ElementArr, n + 1)
end
