Read a .txt file and convert it into an array

I have to read a file.txt of data. The file.txt is written in this format:

150,1,2,3,4,5,6,7,8,9,10,
1;0.0;94.9;62.1;296.6;69.0;530.9;511.9;28.2;17.6;20.8;
2;107.4;0.0;167.3;203.7;77.4;502.4;617.1;101.3;96.9;87.4;
3;61.6;152.5;0.0;339.0;129.8;582.9;450.7;65.2;78.4;70.8;
4;296.7;204.0;356.6;0.0;279.2;426.0;806.4;288.4;286.2;274.4;414.2;
5;60.5;78.5;120.3;280.1;0.0;514.5;570.2;68.8;49.9;54.9;

the real file has 151 line by 151 column but i shorter it to be more easy to read.

I have to make an array of this data file to use easily the data in it. The first line and first column of the data file could be remove

file = fopen('MatriceDistances2.txt', 'rt');
                 
        if file ~= -1
        
        text = fgetl(file);
        while(~feof(file))
            line = fgetl(file);
            text = char(line,text);          
                     
        end
        fclose(file);
        end

I thought using char to concatenate but seam doesn't work with string.

What should I do?

readmatrix can probably handle it, with header lines set to 1. Or readtable if you do not have r2019b or later.
