convert char to double in matlab: str2double-CodePudding

X= 1:63;
n = 6;
% Y = int2bit(X,n)
y=dec2bin(X, n)

with this example I tried str2double(y) and got NaN

What is a problem?

CodePudding user response：

str2double will only convert text that represents real or complex scalar values. Where y is a char array of binary values. It is basically interpreting y as one large integer. Hence, it will return NaN or Inf depending on the version of MATLAB you are using.

CodePudding user response：

You can use convertCharsToStrings and then use str2double

e.g

for i = 1:length(y)
  tempvar = convertCharsToStrings(y(i,:));
  x1(i) = str2double(tempvar);
end

OR if you just want to convert all string into double then use

arrayfun(@(x)str2double(convertCharsToStrings(x)),y,'Uniformoutput',false)
