how to convert char data to Double?

I have a data like

0.104895105
0.112244898
0.139534884

I converted it to binary but it becomes a char data after conversion . how can i convert back to double so that nnstart can take it as input.

kindly help me with it . tx

How did you convert it to binary? Please show the MATLAB code you used to do this.

nnms is Nonlinear Normal Modes ?

@james I used MyNum2Bin(A,4,0,1)

@walter sorry its nnstart

[Walter Roberson]

We have no idea what the code is for MyNum2Bin

[Amit Mishra]

@walter Good Morning. Sorry for the delay. here is the code you requested.

function [y]=MyNum2Bin(x,NumOfBit, Min,Max)

P= ((x - Min) *(2^NumOfBit-1))/(Max-Min)
% if P >1
%     y =dec2bin(P,NumOfBit)
% else
%     X=abs(P)
%     y=dec2bin(X,NumOfBit)
% end
% if P >1
    y =dec2bin(abs(P),NumOfBit)
% else
%     X=abs(P)
%     y=dec2bin(X,NumOfBit)
% end

In this case i dont have any -ve value. So hope i should not be worried. Anyway tx for the point out the error. Please can you give me a code which can 1. if i have 3 column of data 2. convert the data to binary 3. concat it to one data 4. transpose the concated data 5. and take it as input. Thanks

Answer 1

t = MyNum2Bin(A,4,0,1);    %your existing call
u = t - '0';               %now it is 0 and 1's

Note: your MyNum2Bin code treats negative values as positive values.

Please can you give me a code which can

1. if i have 3 column of data
2. convert the data to binary
3. concat it to one data
4. transpose the concated data
5. and take it as input.

Avec = reshape( (dec2bin(floor(A*16), 4) - '0').', 1, []);

"Take it as input" is too vague. Take it as input to what? And what format does the input require?
