simple code for the log computation

Hello,

Please can anyone help me with a short code to do the following computation below

X = { 1, 2, 3, 5, 6}

M1 = log10(X(:,1));

M2 = log10(X(:,2));

M3 = log10(X(:,3));

M4 = log10(X(:,4));

Thanks in advance

Tino

Since ‘X’ is a cell array, you first must convert it to a double array, here using ‘[X{:}]’:

X = { 1, 2, 3, 5, 6};
M = log10([X{:}])

producing:

M =
         0    0.3010    0.4771    0.6990    0.7782

Please do not name them ‘M1’...‘M4’. Keep them as a single array, and refer to them that way. If you want them to be individual elements of a cell array, use the num2cell function.

X = [1, 2, 3, 5, 6];
M = log10(X);
