Use find -

%Sample data
mat = magic(4);
mat = [mat; 1 4 9 16]

mat = 5x4

16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1 1 4 9 16

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

%Get the maximum value
val = max(mat, [], 'all')

val = 16

%% Find the indices of all occurences of the max value
%Linear indices
idx = find(mat==val)

idx = 2x1

1 20

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

%Subscript indices
[r,c] = find(mat==val)

r = 2x1

1 5

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

c = 2x1

1 4

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

Note - Use tolerance to compare for floating point values.
