i want perform following function using if statement has variables in it. consider 3 cell arrays a, b , c of size 16 x 16 each.for example i'm taking 4 x 4 cell arrays.
= b c d b = c b d c = 0 2 1 3 d c b b d c 3 2 3 1 c b d b d 2 1 0 1 b d c d a c 3 2 2 2 with respect values in c need perform functions on , b follows,
if c == 0 out = b; elseif c == 1 out = xx(a,b); elseif c == 2 out = complement (b); elseif c == 3 out = nx(a,b); end here complement, xx , nx functions called. tried following code somehow 'if' statement making hard results. i've defined functions code used perform above operation.
i=1:1:16 j=1:1:16 if c(i,j) == 0 o(i,j) = b(i,j); elseif c(i,j) == 1 o(i,j) = xx(a(i,j),b(i,j)); elseif c(i,j) == 2 o(i,j) = complement(b(i,j)); elseif c(i,j) == 3 o(i,j) = nx(i,j); end end end the function complement follows
function [q]=complement(p) [w1,w2] = size(p); q = zeros(w1,w2); p1 = cell2mat(p) i=1:1:w1 j=1:1:w2 if p1 == 'a' q(i,j) == 'd'; elseif p1 == 'b' q(i,j) == 'c'; elseif p1 == 'c' q(i,j) == 'b'; elseif p1 == 'd' q(i,j) == 'a'; end end end the function xx follows
function [q] = xx(t,p) t = cell2mat(t); p = cell2mat(p); q(t == 'a' & p == 'a') = 'a'; q(t == 'a' & p == 'b') = 'b'; q(t == 'a' & p == 'c') = 'c'; q(t == 'a' & p == 'd') = 'd'; q(t == 'b' & p == 'a') = 'b'; q(t == 'b' & p == 'b') = 'a'; q(t == 'b' & p == 'c') = 'd'; q(t == 'b' & p == 'd') = 'c'; q(t == 'c' & p == 'a') = 'c'; q(t == 'c' & p == 'b') = 'd'; q(t == 'c' & p == 'c') = 'a'; q(t == 'c' & p == 'd') = 'b'; q(t == 'd' & p == 'a') = 'd'; q(t == 'd' & p == 'b') = 'c'; q(t == 'd' & p == 'c') = 'b'; q(t == 'd' & p == 'd') = 'a'; the function nx similar xx substitution differs. don't know i'm going wrong either in functions or in 'if' statement. when run code first if statement , 'first if statement' complement function alone getting executed, remaining functions not performed. thanks.
if a, b, c , o cell arrays, matlab not proceed c(i,j) == 0, since c(i,j) cell array , 0 numerical.
instead pop error (undefined function 'eq' input arguments of type 'cell').
if running first piece of code script, have check on workspace , see c , c(i,j) is.
if want keep a, b, c , o cell arrays, suggest using cell array element operators such c{i,j} == 0, o{i,j} = complement(b(i,j)) since b(i,j) cell output of complement function numerical.
