Hi,
Thank you all.
I would like to read a values from a string which has text, values, space, etc., as shown below.
I would like to take only integer and floating values in the shown content shown in bold text.
There is one space in the starting of each line in the string of bold text.
I donot require any other text in the following.
File C:\Users\Black\Desktop\
TABLE: "PROGRAM CONTROL"
ProgramName=aa Version=21.2.0 ProgLevel=Ultimate LicenseNum=3010*1D7V2883PA2XZJW LicenseOS=Yes LicenseSC=Yes LicenseHT=No CurrUnits="C" SteelCode="b" ConcCode="ACI 318-14" AlumCode="d" _
ColdCode=AISI-ASD96 RegenHinge=Yes
TABLE: "movements"
k=1 Type=NonDirHist StepType=Time StepNum=0 C1=0 C2=0 U3=0 G1=0 R2=0 R3=0
k=1 ype=NonDirHist StepType=Time StepNum=0.1 C1=0 C2=0 U3=0 G1=0 R2=0.0224418047676415 R3=0
k=1 Type=NonDirHist StepType=Time StepNum=0.2 C1=0 C2=0 U3=0 G1=0 R2=0.0261030403456047 R3=0
k=1 Type=NonDirHist StepType=Time StepNum=0.3 C1=0 C2=0 U3=0 G1=0 R2=0.0352000343350302 R3=0
END TABLE DATA
Thank you

Is the spelling mistake on the second line of the table really in the original data? (Type -> ype)

Here an approach which returns a table, which might be more useful for accessing your data:
T = readtable('ex.txt', 'NumHeaderLines',5, 'Delimiter',{'=',' '}, ...
'MultipleDelimsAsOne',true, 'LeadingDelimitersRule','ignore',...
'MissingRule','omitrow')
C = cellstr(mode(categorical(T{:,1:2:end}),1));
T = T(:,2:2:end);
T.Properties.VariableNames = C

hello
try this
Str = readlines('ex.txt');
ind1 = find(contains(Str,'TABLE: "movements"'));
ind2 = find(contains(Str,'END TABLE DATA'));
Str = Str(ind1+1:ind2-1);
B = regexp(Str,'\d+(\.)?(\d+)?','match');
% convert string to num array
for ci = 1:numel(B)
out(ci,:) = str2double(B{ci});
end
