How do i assign value of a sub-cell element to a variable

function [g]= rock(s, m, h)

rock ({{[7,6,4,8,7,9,1,12], [9,6], 31}
         {[9,3,5,8,0,1,1,1,15], [10,10]}
         {[0,0,2,4,0,0,11], [3,4], 26}}, 55,45)

if i pass this i want to add -[7,6,4,8,7,9,1,12] = 54 and [9,6] = 15

i want to assign 7 to a variable and then run a loop uptil the end of the first element (i.e-12) so i can add them. How can i do that?

when i use cell2mat

b=cell2mat(s{1,1});

x=sum(b)

it adds up all the elements if the cell array (i.e [7,6,4,8,7,9,1,12], [9,6], 31) instead of first element

{sum([7,6,4,8,7,9,1,12]), sum([9,6]), 31}

Is this what you wanted?

[shubham shubham]

yes but i want to do it inside the function and not in the command window

[Ajay Kumar]

function [g]= Untitled(s, m, h)
s = [sum(s{1,1}) sum(s{1,2}) sum(s{1,3})];
disp(s);

[shubham shubham]

it's showing me this error

Error using sum

Invalid data type. First argument must be numeric or logical.

Error in score (line 8)

x=sum(s{1,1});

[Ajay Kumar]

what are you passing into s?

could you write it here.

[shubham shubham]

b=cell2mat(s{1,1});

x=sum(b)
