Convert character array or string to numeric array collapse all in pageSyntax X = str2num(txt) X = str2num(txt,Evaluation=method) [X,tf] = str2num(txt)Description X = str2num(txt) converts a character array or string scalar to a numeric matrix. The input can include spaces, commas, and...
= str2num(txt)converts a character array or string scalar to a numeric matrix. The input can include spaces, commas, and semicolons to indicate separate elements. Ifstr2numcannot parse the input as numeric values, then it returns an empty matrix. Thestr2numfunction does not convert cell array...
c = cell(size(A)) creates a cell array the same size as A containing all empty matrices. c = cell(javaobj) converts a Java array or Java object javaobj into a MATLAB cell array. Elements of the resulting cell array will be of the MATLAB type (if any) closest to the Java array ...
Serge on 2 Jun 2016 Open in MATLAB Online str2double is much slower then str2num for a char array and speed is an important aspect of this question. ThemeCopy t1001 = num2str(rand(1001,1)); t1000 = t1001(1:1000,:); ...
