how to form a matrix with non-numeral entries and then set conditions for each case

I want to form a 1*n matrix which have enries of only two cases (like h and c) which are non-numeral as below:

A[1,n]={'h','c'}

A[1,n]=[h c h h h ......c]

and then set a condition if the case is "h" or "c", like

for i=1:n

If A[1,i]==h

Statement

end

However this way of forming code is not correct

I would really appreciate if I cn have your support.

NOH=3;
NOC=2;
Tetta=70*pi/180
for i=1:NOC+NOH
A(1,i)={'h','c'};
A(1,i)=input ('Please enter orientation of ith layer:');
if A(1,i)==h
t_h(i)=0.36
else if A(1,i)==c
        t_c(i)=0.85
    end
end
end

I have made some corrections in your code

clc;clear all;close all
NOH=3;
NOC=2;
Tetta=70*pi/180
A = {}

for i=1:NOC+NOH
i
A(1,i) = input ('Please enter orientation of ith layer:');
if strcmp(A(1,i), 'h') % use strcmp to compare string
		               % Do not use == for string comparison
t_h(i) = 0.36
elseif strcmp(A(1,i), 'c')
        t_c(i) = 0.85
    end
end

This would require that the user would have to know to enter

{'h'}

or

{'c'}

in response to the input prompt, complete with the bracket and quote marks

I suggest it would make more sense to use

A{1,i} = input ('Please enter orientation of ith layer:', 's');
if strcmp(A{1,i}, 'h') % use strcmp to compare string
		               % Do not use == for string comparison
t_h(i) = 0.36
elseif strcmp(A{1,i}, 'c')
        t_c(i) = 0.85
    end

Dear Awais

Thanks for your suggestions. it was really helpful. however when I run the code suggested by you, there is still a problem.

When I run this code, according to second line of the for loop, I have to choose between "h" and "c". when I choose either of them I would receive a message that c or h is not defined.

In the other case when before for loop, I put A{'h','c'} rather than A{}, it still does not work.

I would be happy to have your support on this matter too.

[Awais Saeed]

Either enter your values as 'h' or 'c' (with quote marks) or replace input with

A{1,i} = input ('Please enter orientation of ith layer:', 's');

to be able to enter h and c (without any quote marks).

I sincerely appreciate your both (awais and walter) support. now it works
