在MATLAB中将字母映射为整数 [英] Mapping letters to integers in MATLAB

问题描述

函数 arithenco 要求输入消息为正整数序列.因此，我需要使用以下映射将消息转换为数字序列message_int.

The function arithenco needs the input message to be a sequence of positive integers. Hence, I need convert a message into a sequence of numbers message_int, by using the following mapping.

"A"→1，"C"→2，"G"→3，"T"→4.

‘A’→1, ‘C’→2, ‘G’→3, ‘T’→4.

推荐答案

据我了解，您所使用的字母仅包含四个值A，C，G，T(我想是DNA序列).

From what I understand, the alphabet you are using contains only four values A,C,G,T (DNA sequences I suppose).

简单的比较就足够了:

seq = 'TGGAGGCCCACAACCATTCCCTCAGCCCAATTGACCGAAAGGGCGCGA';
msg_int = zeros(size(seq));
msg_int(seq=='A') = 1;
msg_int(seq=='C') = 2;
msg_int(seq=='G') = 3;
msg_int(seq=='T') = 4;
